* libsandbox: handle broken kernel headersMike Frysinger2012-06-231-0/+11
| | | | | | | | Sometimes the struct in asm/ptrace.h is too small for what the kernel actually writes. Check to see which struct is larger (the one that the kernel declares or the C library declares), and use that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* libsandbox: create more defines for gcc attributesMike Frysinger2012-06-231-0/+2

* libsandbox: mark internal fds with O_CLOEXECMike Frysinger2012-03-071-0/+4
| | | | | | We don't want to bleed these across forks/execs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* libsandbox: delay trace_regs #error until useMike Frysinger2011-07-081-1/+2
| | | | | | | Don't error out if we're missing trace_regs, but we don't ever actually use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* libsandbox: add support for tracing Blackfin/PARISC systemsMike Frysinger2009-04-081-0/+8

* libsandbox: handle symlinks properlyMike Frysinger2009-03-081-0/+1
| | | | | | | | | | | Make sure we handle edge cases that involve symlinks and functions that operate on symlinks. This includes newer style *at functions that can go between operating on symlinks and operating on the linked files, and on symlinks to files that live in explicitly denied paths.

* add checks for signal() return typesMike Frysinger2009-02-181-0/+10
| | | | | | | | | Some systems use sighandler_t while others use sig_t. Add a configure check so that we can assume sighandler_t is always available. URL: http://bugs.gentoo.org/259507 Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reported-by: Javier Villavicencio <the_paya@gentoo.org>
* libsandbox: create hidden targets for most functionsMike Frysinger2009-02-181-0/+1
| | | | | | | | In case we want to access a standard function unwrapped, create hidden functions that do just that. This creates a standard for most functions of the form sb_unwrapped_foo(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* fix environ checkMike Frysinger2009-02-171-1/+1
| | | | | | | | | AC_CHECK_DECL will always create the relevant define and only differ in the actual value (0 or 1). URL: http://bugs.gentoo.org/258365 Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reported-by: Javier Villavicencio <the_paya@gentoo.org>

* define AT_FDCWD for older systemsMike Frysinger2008-12-231-0/+7
| | | | | | | | If the system is not up-to-date with latest POSIX, then setup AT_FDCWD ourself so that things build. Considering how we actually use the value, this shouldn't cause any problems ... Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* handle MAP_ANON on *BSD systemsMike Frysinger2008-12-231-0/+4
| | | | | | | Some systems (like the BSDs) do not define MAP_ANONYMOUS but rather just MAP_ANON. So handle it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
