| 26-Nov-2021 |
christos | Remove #error, fixes the build. I don't understand why this would not work
on big endian. We use this construct to convert pointers everywhere else.
|
| 1.23 |
| 01-Nov-2021 |
thorpej | Use "stack_t" instead of "struct sigaltstack", as the former is the
newer standardized name. NFC.
|
| 1.22 |
| 19-Sep-2021 |
thorpej | Add routines to convert from linux32 to native sigevent_t.
|
| 1.21 |
| 07-Sep-2021 |
riastradh | sys/compat: Memset zero before copyout.
Just in case of uninitialized padding which would lead to kernel
stack disclosure. If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

maxv | branches: 1.20.8;
Fix info leaks in sigaltstack.

christos | branches: 1.19.4; 1.19.8;

XXX: pullup-8
|
| 1.18 |
| 08-Mar-2015 |
christos | branches: 1.18.10;
fix inconsistent names
|
| 1.17 |
| 18-Nov-2013 |
chs | branches: 1.17.4; 1.17.6; 1.17.12;
implement the *at() syscalls.
bring the unimplemented syscall list up to date.
|
| 1.16 |
| 10-May-2012 |
christos | branches: 1.16.2; 1.16.4;
Fix rt_sigtimedwait():
It is wishful thinking that:
1. declaring a 32 bit syscall with 64 bit pointers
2. passing a struct with 32 bit pointers to a 64 bit function
is going to work.
|
| 1.15 |
| 18-Nov-2011 |
christos | branches: 1.15.4; 1.15.6;
remove incorrect assertions (the len passed is the size of the bsd structure
not the linux one)
|
| 1.14 |
| 18-Nov-2011 |
christos | add sigtimedwait support
|
| 1.13 |
| 08-Jun-2009 |

njoly | branches: 1.9.2;
Add rt_sigpending syscall.
|
| 1.8 |
| 24-Apr-2008 |
ad | branches: 1.8.2; 1.8.4; 1.8.6; 1.8.8;
Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.
Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.
|
| 1.7 |
| 20-Dec-2007 |
dsl | branches: 1.7.6; 1.7.8;
Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.
|
| 1.6 |
| 11-Dec-2007 |
lukem | use __KERNEL_RCSID()
|
| 1.5 |
| 08-Dec-2007 |
dsl | branches: 1.5.2; 1.5.4;
ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...
|
| 1.4 |
| 18-Mar-2007 |
dsl | branches: 1.4.8; 1.4.10; 1.4.18;
Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
|
| 1.3 |
| 16-Mar-2007 |
dsl | remove all the double (and triple) casts used to convert 32bit userspace
pointers to and from 64bit kernel pointers. Instead use the defines
NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64)
to write a 32bit pointer throughout.
The 32bit pointer is now a struct to enforce the above.
amd64 (with linux emul) and sparc64 will both compile (when the arch stuff
goes in soon), and amd64 still runs some i386 binaries.

| 1.2 |
| 15-Feb-2007 |
ad | branches: 1.2.2; 1.2.6; 1.2.8; 1.2.10;
Fix COMPAT_LINUX32.
|
| 1.1 |
| 09-Feb-2006 |
manu | branches: 1.1.2; 1.1.10; 1.1.16; 1.1.22;
Add initial (but unfinished) COMPAT_LINUX32 for amd64. This is good enough so
that the i386 license manager part of amd64 version of Fluent works.
While I'm here, add SysV IPC to COMPAT_LINUX/amd64

sys/compat: Memset zero before copyout.
Just in case of uninitialized padding which would lead to kernel
stack disclosure. If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

Fix info leaks.
Fix stupid bugs in linux_sys_shmctl(): the index could be out of bound
(page fault) and there was no proper locking.
Maybe we should just remove LINUX_SHM_STAT, like compat_linux32.
Remove printf.
When dealing with an unknown value, set -1, to prevent (harmless)
uninitialized accesses later.
Add a default case, don't call sys_ioctl() with an uninitialized 'com'
argument.
Fix error handling, returns an errno, not -1.
Put the printf under DEBUG_LINUX.
Hum, don't forget the 'pid' argument, otherwise we're not gonna go very
far.
Don't read data from userland directly. This simply does not work on any
recent x86 CPU (thanks to SMAP) and all architectures that forbid direct
access to userland from the kernel. But I guess no one noticed because no
one ever uses compat_linux, right?
Hum, don't pass an mbuf to realloc(). Inspired from copyin32_msg_control().
Fix memory leak.
I don't see the point in having this useless printf, but add a '\n' to it,
so that it at least displays useless stuff correctly.
Hum, remove incorrect assignment. Userland could have passed a smaller
namelen, and the uninitialized bytes from sb_data were being used later in
the network stack.
