- fix a race where the driver could end up sending a close_con_req after an abort_rpl. In c4iw_ep_disconnect(), send abort or close request with the ep mutex held. - fix a hang where driver fails to wake up when a connection is reset during a normal close. Wake up any waiters in the interrupt path, and correctly cleanup after rdma_fini() failures.

The driver was never really waiting for RDMA_WR/FINI completions because the condition variable used to determine if the completion happened was never reset, and this condition variable is reused for both connection setup and teardown. This causes various driver crashes under heavy loads due to releasing resources too early. The fix is to use atomic bits to correctly reset the condition immediately after the completion is detected.

Concurrent ingress CLOSE and ULP ABORT operations causes a crash due to a race condition where the close path releases the EP lock and then tries to move the QP state to CLOSED. This must be done inside the EP lock to avoid the race. Signed-off-by: NSteve Wise <swise@opengridcomputing.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

Move the connection setup/teardown paths to the workq thread removing spin lock/irq disable requirements for these paths. This allows calls down to the LLD for EP and QP state transition actions to be atomic with respect to processing CPL messages coming up from the HW. Namely, calls to rdma_init() and rdma_fini() can now be called with the mutex held avoiding many race conditions with the abort path. The QP spinlock is still used but only to manipulate the qp state. This allows the fastpaths, poll, post_send, and pos_recv, to run in the irq context.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

This can cause a crash in t3_l2t_send_slow() and other places where the l2t entry is used. The fix is to defer releasing these resources until all endpoint references are gone.
