2023-03-04configure: Use LT_INIT from libtool 2 instead of deprecated AC_PROG_LIBTOOLAlan Coopersmith1-2/+3
AC_PROG_LIBTOOL was replaced by LT_INIT in libtool 2 in 2008, so it's time to rely on it. Clears autoconf warnings: configure.ac:18: warning: The macro `AC_PROG_LIBTOOL' is obsolete. configure.ac:18: You should run autoupdate. aclocal.m4:3640: AC_PROG_LIBTOOL is expanded from... configure.ac:18: the top level libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac, libtoolize: and rerunning libtoolize and aclocal.

2022-12-04ICEmsg: Fix C++ interoperability error due to static_assert defineArsen Arsenović1-1/+1
Commit 0269c687e954db7aca2a4344e32cb203315a00b6 added a static_assert helper that gets defined to blank if left undefined by assert.h. As this is not a macro in other languages that use this header, this can lead to a compile-time error. Bug: https://bugs.gentoo.org/884369

2022-11-23configure: Use AC_SYS_LARGEFILE to enable large file supportAlan Coopersmith1-0/+3
The only files libICE operates on are .ICEauthority files, which it only uses internally and does not make available to other code, so there is no concern about ABI mismatch here. While .ICEauthority files should never be more than 2gb in size, they may be stored on filesystems with large inodes. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

2022-10-06Switch from libbsd to libbsd-overlayGuillem Jover3-10/+7
This is the preferred usage form for libbsd, as it makes the code more portable and requires no special includes for libbsd, by transparently injects the needed standard headers that would be used on a BSD. Signed-off-by: Guillem Jover <guillem@hadrons.org>

2022-09-07IceFlush: signal fatal I/O error if bufptr is past end of bufferAlan Coopersmith1-0/+10
It should never happen, but has been possible in the past when we didn't handle buffer checks properly - this would help us catch it if a similar mistake ever happens again (or the wrong memory pointer gets corrupted by something else). Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

If there's not room for it in the buffer, we already set pData to NULL, but still set the outbufptr to include the space, which could lead to IceFlush() reading past the end of the buffer. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

2022-04-30ConnectToPeer: be doubly sure that use-after-free doesn't happenAlan Coopersmith1-0/+1
This resolves an issue reported by the Oracle Parfait static analyzer: Error: Use after free Use after free [use-after-free] (CWE 416): Use after free of pointer trans_conn at line 566 of lib/libICE/src/connect.c in function 'ConnectToPeer'. trans_conn previously freed with _IceTransClose at line 532 trans_conn was allocated at line 525 with _IceTransOpenCOTSClient even though I believe this is already handled by the 'if (madeConnection) { ... } else trans_conn = NULL;' block, but the analyzer apparently doesn't follow that logic, while this simple change makes it obvious.

Assigning and testing a value in a single statement hinders code clarity and may confuses static code analyzers. Separate the assignment and the test for clarity. Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>
2019-04-10_IceRead: Avoid possible use-after-freeOlivier Fourdan1-1/+0
`_IceRead()` gets called from multiple places which do not expect the connection to be freed. Do not free the connection data in `_IceRead()` to avoid potential use-after-free issue in the various callers. The connection data will be freed eventually in `ProcessWantToClose()`, so not freeing it in `_IceRead()` should not introduce an memory leak. Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>

If we find that $XDG_RUNTIME_DIR is set (and $ICEAUTHORITY is not), then the ICEauthority file is stored in the XDG_RUNTIME_DIR instead of the home directory, and without a leading dot. https://bugs.freedesktop.org/show_bug.cgi?id=49173 Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>
2019-03-24authutil: fix an out-of-bounds accessAllison Lortie1-2/+2
There is a theoretical edge case where the $HOME environment variable could be set to the empty string. IceAuthFileName() unconditionally checks index 1 of this string, which is out of bounds. Fix that up by rejecting empty strings in the same way as we reject NULL. https://bugs.freedesktop.org/show_bug.cgi?id=49173 Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>
