arp: fix the behavior on detecting an address duplication without IPv4 DAD

On receiving an ARP request that has the same source protocol address as
the own address, i.e., address duplication, the original behavior of
a kernel prior to supporing IPv4 DAD is to send an ARP reply. It is
the same with a latest kernel with DAD enabled. However, a latest
kernel without DAD sends back an GARP packet. Restore the original
behavior.

inet: send GARP on link up if DAD is disabled

This behavior was accidentally removed at rev 1.233.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.

No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

PR pkg/57445

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

Fix markup of libh_ MKDEBUGLIB=yes only files

TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

PR pkg/57445

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

Fix markup of libh_ MKDEBUGLIB=yes only files

TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

One library defines a symbol and _doesn't_ use it, so it has no

and then two other libraries use it in different ways.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol

computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.

No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.

Fix MKDEBUGLIB build by adding these installed files to the debug

XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no

and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

enabled by borrowing the rdbg_symname() macro from arch/x86_64.

2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

PR pkg/57445

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

Fix markup of libh_ MKDEBUGLIB=yes only files

TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

PR pkg/57445

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

Fix markup of libh_ MKDEBUGLIB=yes only files

TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

PR pkg/57445

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

Fix markup of libh_ MKDEBUGLIB=yes only files

TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Sprinkle tls debug messages.

ld.elf_so: Make tls alloc debug messages more detailed and greppable.

ld.elf_so: Test variations on PR toolchain/50277.

ld.elf_so: Test extern dynamic TLS too.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.

ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.

ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.

ld.elf_so: Test dynamic-then-static abuse via ctor.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.

Fix interactions of initial-exec TLS model and dlopen

(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.

This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.

(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

PR pkg/57445

Fix MKDEBUGLIB build by adding these installed files to the debug
set list.

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.

Fix markup of libh_ MKDEBUGLIB=yes only files

TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!
