joerg | Export the guard size of the main thread via vm.guard_size. Add a
complementary writable sysctl for the initial guard size of threads
created via pthread_create. Let the existing attribut accessors do the
right thing. Raise the default guard size for threads to 64KB.

libpthread_dbg(3) deletion from the base distribution
libpthread_dbg(3) is a remnant library from the M:N thread model
(pre-NetBSD-5.0) API to introspect threads within a process and for use
of debuggers.
Currently in the 1:1 model it's not used in GDB neither in LLDB and it's
not either planned to be used. It's current function to read pthread_t
structures is realizable within a regular debugger capable to
instrospect objects within a tracee (GDB, LLDB...).
Remaining users of this API can still use this library from
pkgsrc/devel/libpthread_dbg.

ad | Update.
|
| 1.12 |
| 13-Nov-2007 |
ad | Mutexes:
- Play scrooge again and chop more cycles off acquire/release.
- Spin while the lock holder is running on another CPU (adaptive mutexes).
- Do non-atomic release.
Threadreg:
- Add the necessary hooks to use a thread register.
- Add the code for i386, using %gs.
- Leave i386 code disabled until xen and COMPAT_NETBSD32 have the changes.

Remove the PTHREAD_SA option. If M:N threads is reimplemented it's
better off done with a seperate library.

ad | Don't grab the state lock to check for cancellation around condition
variables, as _lwp_wakeup/lwp_park provide the necessary barrier.

yamt | fix a race between pthread_exit and pthread_create.
inefficient, but better than crashing.

jdolecek | pthread_kill() was implemented, remove from list
pthread_cond_timedwait() now works even before SA initialization, but some
other routines do not; update the paragraph for this

|
| 1.1 |

file TODO was initially added on branch nathanw_sa.
|
| 1.1.2.19 |

thorpej | Implement recursive and errorcheck mutexes.
|
| 1.1.2.18 |
| 07-Jan-2003 |
thorpej | In the "ideas to play with" section, make a note about registers
reserved by the ABI for thread-specific data.
|
| 1.1.2.17 |
| 30-Dec-2002 |
thorpej | Add support for using RAS lock primitives on uniprocessors where
RAS is available.
|
| 1.1.2.16 |
| 30-Oct-2002 |
skrll | Nathan added pthread_rwlock.c
|
| 1.1.2.15 |
| 02-Oct-2002 |
thorpej | One more signal-reliated item.
|
| 1.1.2.14 |
| 02-Oct-2002 |
thorpej | libc:
Internally rename __sigaction14 to __libc_sigaction14. Provide a
weak alias of __sigaction14 -> __libc_sigaction14.
libpthread:
Use __libc_sigaction14 to actually register the signal handler, rather
than using __sigaction_sigtramp() directly with a hard-coded trampoline
version. While we don't actually use the libc trampoline, we want to
avoid depending on any COMPAT_* kernel options down the road (this is
already the case for the VAX port).
Be explicit about which version of the signal interface we're interposing
(...14), and build pthread_sig.c with __LIBC12_SOURCE__ (required to get
the libc-internal interfaces).

| 1.1.2.13 |

thorpej | ...and another.

need to be written.
|

Always include a 1MB guard area beyond the end of stack. While ASLR will
normally create a guard area as well, this provides a deterministic area
for all binaries.
Mitigates the rest of CVE-2017-1000374 and CVE-2017-1000375 from
Qualys.
Revert for the moment, creates problems on i386.
Recommit exec_subr.c revision 1.79:
Always include a 1MB guard area beyond the end of stack. While ASLR will
normally create a guard area as well, this provides a deterministic area
for all binaries.
Mitigates the rest of CVE-2017-1000374 and CVE-2017-1000375 from
Qualys.
Additionally, change VM_DEFAULT_ADDRESS_TOPDOWN to include
user_stack_guard_size in the size reservation.
Update VM_DEFAULT_ADDRESS32_TOPDOWN to include guard area.
Export the guard size of the main thread via vm.guard_size. Add a
complementary writable sysctl for the initial guard size of threads
created via pthread_create. Let the existing attribut accessors do the
right thing. Raise the default guard size for threads to 64KB.
