Tavis Ormandy pointed out that do_io_submit does not do proper bounds checking on the passed-in iocb array: if (unlikely(nr < 0)) return -EINVAL; if (unlikely(!access_ok(VERIFY_READ, iocbpp, (nr*sizeof(iocbpp))))) return -EFAULT; ^^^^^^^^^^^^^^^^^^ The attached patch checks for overflow, and if it is detected, the number of iocbs submitted is scaled down to a number that will fit in the long. This is an ok thing to do, as sys_io_submit is documented as returning the number of iocbs submitted, so callers should handle a return value of less than the 'nr' argument passed in. Reported-by:

My macbook infrared remote control was broken by commit bd25f4dd ("HID: hiddev: use usb_find_interface, get rid of BKL"). This device appears in dmesg as: apple 0003:05AC:8242.0001: hiddev0,hidraw0: USB HID v1.11 Device [Apple Computer, Inc. IR Receiver] on usb-0000:00:1d.2-1/input0 It stopped working as lircd was getting ENODEV when opening /dev/usb/hiddev0. AFAICS hiddev_driver is a dummy driver so usb_find_interface(&hiddev_driver) does not find anything. The device is associated with the usbhid driver, so let's do usb_find_interface(&hid_driver) instead. $ ls -l /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver lrwxrwxrwx 1 root root 0 2010-09-12 16:28 /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver -> ../../../../../../bus/usb/drivers/usbhid Signed-off-by:

Mathieu reported bad latencies with make -j10 kind of kbuild workloads - which is mostly caused by us scheduling with a too coarse granularity. Reduce the minimum granularity some more, to make sure we can meet the latency target. I got the following results (make -j10 kbuild load, average of 3 runs): vanilla: maximum latency: 38278.9 µs average latency: 7730.1 µs patched: maximum latency: 22702.1 µs average latency: 6684.8 µs Mathieu also measured it: | | * wakeup-latency.c (SIGEV_THREAD) with make -j10 | | - Mainline 2.6.35.2 kernel | | maximum latency: 45762.1 µs | average latency: 7348.6 µs | | - With only Peter's smaller min_gran (shown below): | | maximum latency: 29100.6 µs | average latency: 6684.1 µs | Reported-by:

The NFSv4 client's callback server calls svc_gss_principal(), which is defined in the auth_rpcgss.ko The NFSv4 server has the same dependency, and in addition calls svcauth_gss_flavor(), gss_mech_get_by_pseudoflavor(), gss_pseudoflavor_to_service() and gss_mech_put() from the same module. The module auth_rpcgss itself has no dependencies aside from sunrpc, so we only need to select RPCSEC_GSS. Reported-by:

Hi, An NFS client executes a statfs("file", &buff) call. "file" exists / existed, the client has read / written it, but it has already closed it. user_path(pathname, &path) looks up "file" successfully in the directory-cache and restarts the aging timer of the directory-entry. Even if "file" has already been removed from the server, because the lookupcache=positive option I use, keeps the entries valid for a while. nfs_statfs() returns ESTALE if "file" has already been removed from the server. If the user application repeats the statfs("file", &buff) call, we are stuck: "file" remains young forever in the directory-cache. Signed-off-by:

The maximum size of the authcache is now set to 1024 (10 bits), but on our server we need at least 4096 (12 bits). Increase MAX_HASHTABLE_BITS to 14. This is a maximum of 16384 entries, each containing a pointer (8 bytes on x86_64). This is exactly the limit of kmalloc() (128K). Signed-off-by:

The do_vfs_lock function on fs/nfs/file.c is only called if NLM is not being used, via the -onolock mount option. Therefore it cannot really be "out of sync with lock manager" when the local locking function called returns an error, as there will be no corresponding call to the NLM. For details, simply check the if/else on do_setlk and do_unlk on fs/nfs/file.c. Signed-Off-By:

This is just a minor cleanup: net/sunrpc/clnt.c clarifies the rpc client state machine by commenting each state and by laying out the functions implementing each state in the order that each state is normally executed (in the absence of errors). The previous patch "Fix null dereference in call_allocate" changed the order of the states. Move the functions and update the comments to reflect the change. Signed-off-by:

If rpc_queue_upcall() adds a new upcall to the rpci->pipe list just after rpc_pipe_release calls rpc_purge_list(), but before it calls gss_pipe_release (as rpci->ops->release_pipe(inode)), then the latter will free a message without deleting it from the rpci->pipe list. We will be left with a freed object on the rpc->pipe list. Most frequent symptoms are kernel crashes in rpc.gssd system calls on the pipe in question. Reported-by:

In call_allocate we need to reach the auth in order to factor au_cslack into the allocation. As of a17c2153 "SUNRPC: Move the bound cred to struct rpc_rqst", call_allocate attempts to do this by dereferencing tk_client->cl_auth, however this is not guaranteed to be defined--cl_auth can be zero in the case of gss context destruction (see rpc_free_auth). Reorder the client state machine to bind credentials before allocating, so that we can instead reach the auth through the cred. Signed-off-by:

When you don't use !E or !I but only !F, then it's very easy to miss including some functions, structs etc. in documentation. To help finding which ones were missed, allow printing out the unused ones as warnings. For example, using this on mac80211 yields a lot of warnings like this: Warning: didn't use docs for DOC: mac80211 workqueue Warning: didn't use docs for ieee80211_max_queues Warning: didn't use docs for ieee80211_bss_change Warning: didn't use docs for ieee80211_bss_conf when generating the documentation for it.
