2016-04-17build: fix compilation warnings with _GNU_SOURCEarch3y1-2/+3
Fix the following warnings when building with glibc>=2.20: proc.c:1:0: warning: "_GNU_SOURCE" redefined ioops.c:1:0: warning: "_GNU_SOURCE" redefined xmalloc.c:8:0: warning: "_GNU_SOURCE" redefined Signed-off-by: Arch3y <arch3y@archstrike.org> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2015-02-05xmalloc: Make xrealloc() arguments conform to realloc()Tobias Klauser1-8/+5
xrealloc() has an additional nmemb argument compared to realloc() for which it should serve as a wrapper. Since we always call with nmemb = 1, we might as well remove this argument and thus have xrealloc() conform to the realloc() function prototype. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2015-02-05xmalloc: Remove unnecessary NULL check before realloc()Tobias Klauser1-5/+1
If realloc() is passed NULL as its first argument, it behaves like malloc(), so the check for ptr begin NULL is not necessary Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-06-25xmalloc: Add and use xcallocTobias Klauser1-0/+15
Add a wrapper for calloc which checks for integer overflows in the calculation of the size to allocate. Use xcalloc to allocate an array of objects instead of calculating the size ourselves, which might cause an integer overflow. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-06-12ioops: misc: add dup{,2}_or_die to ioopsDaniel Borkmann1-8/+0
Bail out if it should ever fail. Detected by coverty in the translate_pcap_to_txf() path. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xutils: eliminate xutils, move rest to epoll2Daniel Borkmann1-1/+0
Finally eliminate xutils.{c,h} and move the rest to epoll2. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xutils: break out string handling and lockingDaniel Borkmann1-0/+1
Break out all string handling functions and lockme stuff in order to further eliminate the big code blob in xutils, so that it can be easier maintained. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

We decided to get rid of the old Git history and start a new one for several reasons: *) Allow / enforce only high-quality commits (which was not the case for many commits in the history), have a policy that is more close to the one from the Linux kernel. With high quality commits, we mean code that is logically split into commits and commit messages that are signed-off and have a proper subject and message body. We do not allow automatic Github merges anymore, since they are total bullshit. However, we will either cherry-pick your patches or pull them manually. *) The old archive was about ~27MB for no particular good reason. This basically derived from the bad decision that also some PDF files where stored there. From this moment onwards, no binary objects are allowed to be stored in this repository anymore. The old archive is not wiped away from the Internet. You will still be able to find it, e.g. on git.cryptoism.org etc. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
