7b37f4549b sysctl_security_setidcorename: don't allocate MAXPATHLEN bytes on stack. 2006-06-17 06:54:58 +00:00

5174aa84b6 The UID_MAX limit is not enforced by syscalls such as setreuid(2), 
so I remove the assertion uid >= 0 && uid <= UID_MAX.  This squashes
a bug where Quagga would panic my machine by passing a UID outside
the range [0, UID_MAX].

AFAICT, this restores the historical (pre-kauth) behavior.

It is likely that GIDs do not satisfy the assertion gid >= 0 &&
gid <= GID_MAX, so remove that, too.

Patch from elad.

d05e0bc3e8 Add EAFNOSUPPORT as a possible error if the address family is not 
supported.  This adds further differentiation between which argument to
socket(2) caused the error.  No longer are invalid domain (address family)
errors classified as ENOPROTOSUPPORT errors.  This should make socket(2)
conform to current POSIX and X/Open standards.  Fixes PR/33676.

de4337ab21 merge FreeBSD timecounters from branch simonb-timecounters 
- struct timeval time is gone
  time.tv_sec -> time_second
- struct timeval mono_time is gone
  mono_time.tv_sec -> time_uptime
- access to time via
	{get,}{micro,nano,bin}time()
	get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)
- further reading:

b3e7e1b010 Better implementation of PaX MPROTECT, after looking some more into the 
code and not trying to use temporary solutions.

Lots of comments and help from YAMAMOTO Takashi, also thanks to the PaX
author for being quick to recognize that something fishy's going on. :)

Hook up in mmap/vmcmd rather than (ugh!) uvm_map_protect().

Next time I suggest to commit a temporary solution just revoke my
commit bit.

W^X mappings.

Disabled by default.

First proposed in:

More information in:

Read relevant parts of options(4) and sysctl(3) before using!

Lots of thanks to the PaX author and Matt Thomas.
