Bug #61430 [NEW]: Transposed memset() params in sapi/fpm/fpm/fpm_shm.c

From: Operating system: Linux PHP version: 5.4.0 Package: FPM related Bug Type: Bug Bug description:Transposed memset() params in sapi/fpm/fpm/fpm_shm.c Description: ------------ Affects all versions which bundle PHP-FPM. (>=5.3.3) In fpm_shm_alloc there is a call to memset() to initialise the segment. The parameters to memset() are transposed. Since we are [trying to] initialise with 0, but passing 0 to size_t, it silently fails to do anything. Patch attached, tested on 5.3.10 and 5.4.0. -- Edit bug report at https://bugs.php.net/bug.php?id=61430&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61430&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61430&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61430&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61430&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61430&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61430&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61430&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61430&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61430&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61430&r=support Expected behavior: https://bugs.php.net/fix.php?id=61430&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61430&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61430&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61430&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61430&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61430&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61430&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61430&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61430&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61430&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61430&r=mysqlcfg
