Patch FixLibraryStartup.patch
An Ubuntu-specific patch (FixLibraryStartup.patch) causes /proc/self/auxv to be opened on library initialization, but the file is never closed. For long running processes that periodically re-initialize the library (Firefox's plugin-container loading the VLC plugin for me), this leads to the available file descriptors being exhausted.
This is on Precise with libjpeg-turbo8 version 1.1.90+svn733-0ubuntu4. https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1177684 is caused by this issue as well, but have not confirmed this.
Patch is attached. |

[impact]
In precise only, an Ubuntu-specific patch (FixLibraryStartup.patch) causes /proc/self/auxv to be opened on library initialization, but the file is never closed. For long running processes that periodically re-initialize the library (Firefox's plugin-container loading the VLC plugin for me), this leads to the available file descriptors being exhausted.
This also causes https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1177684.
[test case]
Fresh and clean Ubuntu Precise 12.04.2 install
# apt-get install apache2-mpm-itk libapache2-mod-php5 php5-gd
Restart Apache to ensure gd.so is loaded
# for pid in `pidof apache2`; do find /proc/$pid/fd -ls; done | awk '/auxv/ {print $11" "$12" "$13}'
# apache2ctl graceful
# for pid in `pidof apache2`; do find /proc/$pid/fd -ls; done | awk '/auxv/ {print $11" "$12" "$13}'
# apache2ctl graceful
# for pid in `pidof apache2`; do find /proc/$pid/fd -ls; done | awk '/auxv/ {print $11" "$12" "$13}'
.. etc
[regression potential]
This affects patch designed for ARM. Although all it does it properly close the file descriptor, I have not specifically tested it on ARM. |
