Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "663717f65c075eb4c6da7a123041295bd5295cc0", "tree": "5613a3c05449ae2d36f6c70a7ebb4ce63e88f448", "parents": [ "b9fb9ee07e67fce0b7bfd517a48710465706c30a" ], "author": { "name": "Stephen Hemminger", "email": "shemminger@vyatta.com", "time": "Thu Feb 18 14:12:06 2010 -0800" }, "committer": { "name": "David S.

I\n confirmed this with strace. The behaviour differs from Linux\n 2.6.26, where reportedly only one of those recvmsg calls (I think\n the first one) returned the file descriptor.\"\n\nThis bug was introduced by a patch from me titled \"net: unix: fix inflight\ncounting bug in garbage collector\", commit 6209344f5.\n\nAnd the reason is, quoting Kalle:\n\n \"Before your patch, unix_attach_fds() would set scm-\u003efp \u003d NULL, so\n that if the loop in unix_stream_sendmsg() ran multiple iterations,\n it could not call unix_attach_fds() again. But now,\n unix_attach_fds() leaves scm-\u003efp unchanged, and I think this causes\n it to be called multiple times and duplicate the same file\n descriptors to each struct sk_buff.\"\n\nFix this by introducing a flag that is cleared at the start and set\nwhen the fds attached to the first buffer.

By\nvirtue of this all socket create methods are touched. In addition\nthe socket create methods are modified so that they will fail if\nyou attempt to create a socket in a non-default network namespace.\n\nFailing if we attempt to create a socket outside of the default\nnetwork namespace ensures that as we incrementally make the network stack\nnetwork namespace aware we will not export functionality that someone\nhas not audited and made certain is network namespace safe.\nAllowing us to partially enable network namespaces before all of the\nexotic protocols are supported.\n\nAny protocol layers I have missed will fail to compile because I now\npass an extra parameter into the socket creation code.\n\n[ Integrated AF_IUCV build fixes from Andrew Morton... -DaveM ]\n\nSigned-off-by: Eric W.

It modifies the global\nvariables proc_net and proc_net_stat to be per network namespace.\nThe proc_net file helpers are modified to take a network namespace argument,\nand all of their callers are fixed to pass \u0026init_net for that argument.\nThis ensures that all of the /proc/net files are only visible and\nusable in the initial network namespace until the code behind them\nhas been updated to be handle multiple network namespaces.\n\nMaking /proc/net per namespace is necessary as at least some files\nin /proc/net depend upon the set of network devices which is per\nnetwork namespace, and even more files in /proc/net have contents\nthat are relevant to a single network namespace.\n\nSigned-off-by: Eric W.
