2008-01-18Revert adding the packed attribute, as it really doesn't make sense why thatrussell1-1/+1
would do any good. Fix the real bug, which is to do the check to see if the frame came from a translator at the beginning of ast_frame_free(), instead of at the end. This ensures that it always gets checked, even if none of the parts of the frame are malloc'd, and also ensures that we aren't looking at free'd memory in the case that it is a malloc'd frame. (closes issue #11792, reported by explidous, patched by me) git-svn-id: http://svn.digium.com/svn/asterisk/branches/1.4@99081 f38db490-d61c-443f-a65b-d21fe96a405b
2008-01-18Since we're relying on the offset between the frame and the beginning of the ↵russell1-1/+1
translator pvt struct, set the packed attribute to make sure we get to the right place. (potential fix for issue #11792) git-svn-id: http://svn.digium.com/svn/asterisk/branches/1.4@99079 f38db490-d61c-443f-a65b-d21fe96a405b
2008-01-15Commit a fix for some memory access errors pointed out by the valgrind2.txtrussell1-1/+22
output on issue #11698. The issue here is that it is possible for an instance of a translator to get destroyed while the frame allocated as a part of the translator is still being processed. Specifically, this is possible anywhere between a call to ast_read() and ast_frame_free(), which is _a lot_ of places in the code. The reason this happens is that the channel might get masqueraded during this time. During a masquerade, existing translation paths get destroyed. So, this patch fixes the issue in an API and ABI compatible way. (This one is for you, paravoid!) It changes an int in ast_frame to be used as flag bits. The 1 bit is still used to indicate that the frame contains timing information. Also, a second flag has been added to indicate that the frame came from a translator. When a frame with this flag gets released and has this flag, a function is called in translate.c to let it know that this frame is doing being processed. At this point, the flag gets cleared. Also, if the translator was requested to be destroyed while its internal frame still had this flag set, its destruction has been deffered until it finds out that the frame is no longer being processed. Admittedly, this feels like a hack. But, it does fix the issue, and I was not able to think of a better solution ... git-svn-id: http://svn.digium.com/svn/asterisk/branches/1.4@98943 f38db490-d61c-443f-a65b-d21fe96a405b

2006-06-06Merge of the "sdpcleanup" branch. Thanks to John Martin for a lot of testsoej1-1/+2
and some patches (all disclaimed). - Don't change RTP properties if we reject a re-INVITE - Don't add video to an outbound channel if there's no video on the inbound channel - Don't include video in the "preferred codec" list for codec selection - Clean up and document code that parses and adds SDP attachments Since we do not transcode video, we can't handle video the same way as audio. This is a bug fix patch. In future releases, we need to work on a solution for video negotiation, not codecs but formats and framerates instead. git-svn-id: http://svn.digium.com/svn/asterisk/trunk@32597 f38db490-d61c-443f-a65b-d21fe96a405b

2006-04-14This rather large commit changes the way modules are loaded. rizzo1-3/+3
As partly documented in loader.c and include/asterisk/module.h, modules are now expected to return all of their methods and flags into a structure 'mod_data', and are normally loaded with RTLD_NOW | RTLD_LOCAL, so symbols are resolved immediately and conflicts should be less likely. Only in a small number of cases (res_*, typically) modules are loaded RTLD_GLOBAL, so they can export symbols. The core of the change is only the two files loader.c and include/asterisk/module.h, all the rest is simply adaptation of the existing modules to the new API, a rather mechanical (but believe me, time and finger-consuming!) process whose detail you can figure out by svn diff'ing any single module. Expect some minor compilation issue after this change, please report it on mantis http://bugs.digium.com/view.php?id=6968 so we collect all the feedback in one place. I am just sorry that this change missed SVN version number 20000! git-svn-id: http://svn.digium.com/svn/asterisk/trunk@20003 f38db490-d61c-443f-a65b-d21fe96a405b
