2011-01-11phonet: some signedness bugsDan Carpenter1-3/+3
Dan Rosenberg pointed out that there were some signed comparison bugs in the phonet protocol. http://marc.info/?l=full-disclosure&m=129424528425330&w=2 The problem is that we check for array overflows but "protocol" is signed and we don't check for array underflows. If you have already have CAP_SYS_ADMIN then you could use the bugs to get root, or someone could cause an oops by mistake.

2010-10-14Phonet: 'connect' socket implementation for Pipe controllerKumar Sanghvi2-187/+212
Based on suggestion by Rémi Denis-Courmont to implement 'connect' for Pipe controller logic, this patch implements 'connect' socket call for the Pipe controller logic. The patch does following:- - Removes setsockopts for PNPIPE_CREATE and PNPIPE_DESTROY - Adds setsockopt for setting the Pipe handle value - Implements connect socket call - Updates the Pipe controller logic User-space should now follow below sequence with Pipe controller:- -socket -bind -setsockopt for PNPIPE_PIPE_HANDLE -connect -setsockopt for PNPIPE_ENCAP_IP -setsockopt for PNPIPE_ENABLE GPRS/3G data has been tested working fine with this.

2010-10-09Phonet: mark the pipe controller as EXPERIMENTALRémi Denis-Courmont1-2/+2
There are a bunch of issues that need to be fixed, including: - GFP_KERNEL allocations from atomic context (and GFP_ATOMIC in process context), - abuse of the setsockopt() call convention, - unprotected/unlocked static variables... IMHO, we will need to alter the userspace ABI when we fix it. So mark the configuration option as EXPERIMENTAL for the time being (or should it be BROKEN instead?).

2010-10-09Phonet: cleanup pipe enable socket optionRémi Denis-Courmont1-42/+30
The current code works like this: int garbage, status; socklen_t len = sizeof(status); /* enable pipe */ setsockopt(fd, SOL_PNPIPE, PNPIPE_ENABLE, &garbage, sizeof(garbage)); /* disable pipe */ setsockopt(fd, SOL_PNPIPE, PNPIPE_DISABLE, &garbage, sizeof(garbage)); /* get status */ getsockopt(fd, SOL_PNPIPE, PNPIPE_INQ, &status, &len); ...which does not follow the usual socket option pattern. This patch merges all three "options" into a single gettable&settable option, before Linux 2.6.37 gets out: int status; socklen_t len = sizeof(status); /* enable pipe */ status = 1; setsockopt(fd, SOL_PNPIPE, PNPIPE_ENABLE, &status, sizeof(status)); /* disable pipe */ status = 0; setsockopt(fd, SOL_PNPIPE, PNPIPE_ENABLE, &status, sizeof(status)); /* get status */ getsockopt(fd, SOL_PNPIPE, PNPIPE_ENABLE, &status, &len); This also fixes the error code from EFAULT to ENOTCONN.

2010-09-16Phonet: resource routing backendRémi Denis-Courmont1-0/+88
When both destination device and object are nul, Phonet routes the packet according to the resource field. In fact, this is the most common pattern when sending Phonet "request" packets. In this case, the packet is delivered to whichever endpoint (socket) has registered the resource. This adds a new table so that Linux processes can register their Phonet sockets to Phonet resources, if they have adequate privileges. (Namespace support is not implemented at the moment.)

2010-09-16Phonet: remove dangling pipe if an endpoint is closed earlyRémi Denis-Courmont1-1/+26
Closing a pipe endpoint is not normally allowed by the Phonet pipe, other than as a side after-effect of removing the pipe between two endpoints. But there is no way to prevent Linux userspace processes from being killed or suffering from bugs, so this can still happen. We might as well forcefully close Phonet pipe endpoints then. The cellular modem supports only a few existing pipes at a time. So we really should not leak them. This change instructs the modem to destroy the pipe if either of the pipe's endpoint (Linux socket) is closed too early.

2010-05-02net: sock_def_readable() and friends RCU conversionEric Dumazet2-5/+5
sk_callback_lock rwlock actually protects sk->sk_sleep pointer, so we need two atomic operations (and associated dirtying) per incoming packet. RCU conversion is pretty much needed : 1) Add a new structure, called "struct socket_wq" to hold all fields that will need rcu_read_lock() protection (currently: a wait_queue_head_t and a struct fasync_struct pointer). [Future patch will add a list anchor for wakeup coalescing] 2) Attach one of such structure to each "struct socket" created in sock_alloc_inode(). 3) Respect RCU grace period when freeing a "struct socket_wq" 4) Change sk_sleep pointer in "struct sock" by sk_wq, pointer to "struct socket_wq" 5) Change sk_sleep() function to use new sk->sk_wq instead of sk->sk_sleep 6) Change sk_has_sleeper() to wq_has_sleeper() that must be used inside a rcu_read_lock() section. 7) Change all sk_has_sleeper() callers to : - Use rcu_read_lock() instead of read_lock(&sk->sk_callback_lock) - Use wq_has_sleeper() to eventually wakeup tasks. - Use rcu_read_unlock() instead of read_unlock(&sk->sk_callback_lock) 8) sock_wake_async() is modified to use rcu protection as well. 9) Exceptions : macvtap, drivers/net/tun.c, af_unix use integrated "struct socket_wq" instead of dynamically allocated ones. They dont need rcu freeing. Some cleanups or followups are probably needed, (possible sk_callback_lock conversion to a spinlock for example...).

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo6-0/+6
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.
