* net dst: fix percpu_counter list corruption and poison overwrittenXiaotian Feng2010-11-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | There're some percpu_counter list corruption and poison overwritten warnings in recent kernel, which is resulted by fc66f95c. commit fc66f95c switches to use percpu_counter, in ip6_route_net_init, kernel init the percpu_counter for dst entries, but, the percpu_counter is never destroyed in ip6_route_net_exit. So if the related data is freed by kernel, the freed percpu_counter is still on the list, then if we insert/remove other percpu_counter, list corruption resulted. Also, if the insert/remove option modifies the ->prev,->next pointer of the freed value, the poison overwritten is resulted then. With the following patch, the percpu_counter list corruption and poison overwritten warnings disappeared. Signed-off-by: Xiaotian Feng <dfeng@redhat.com> Cc: "David S.

* RDS: Let rds_message_alloc_sgs() return NULLAndy Grover2010-10-313-0/+17
| | | | | | | | | | | | | | | | | Even with the previous fix, we still are reading the iovecs once to determine SGs needed, and then again later on. Preallocating space for sg lists as part of rds_message seemed like a good idea but it might be better to not do this. While working to redo that code, this patch attempts to protect against userspace rewriting the rds_iovec array between the first and second accesses. The consequences of this would be either a too-small or too-large sg list array. Too large is not an issue. This patch changes all callers of message_alloc_sgs to handle running out of preallocated sgs, and fail gracefully. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* RDS: Copy rds_iovecs into kernel memory instead of rereading from userspaceAndy Grover2010-10-311-39/+65
| | | | | | | | | | | | | | | | | | | Change rds_rdma_pages to take a passed-in rds_iovec array instead of doing copy_from_user itself. Change rds_cmsg_rdma_args to copy rds_iovec array once only. This eliminates the possibility of userspace changing it after our sanity checks. Implement stack-based storage for small numbers of iovecs, based on net/socket.c, to save an alloc in the extremely common case. Although this patch reduces iovec copies in cmsg_rdma_args to 1, we still do another one in rds_rdma_extra_size. Getting rid of that one will be trickier, so it'll be a separate patch.

* net: fix rds_iovec page count overflowLinus Torvalds2010-10-311-0/+7
| | | | | | | | | | | | | | | | | | | As reported by Thomas Pollet, the rdma page counting can overflow. We get the rdma sizes in 64-bit unsigned entities, but then limit it to UINT_MAX bytes and shift them down to pages (so with a possible "+1" for an unaligned address). So each individual page count fits comfortably in an 'unsigned int' (not even close to overflowing into signed), but as they are added up, they might end up resulting in a signed return value. Which would be wrong. Catch the case of tot_pages turning negative, and return the appropriate error code.

| * mac80211: fix failure to check kmalloc return value in key_key_readJesper Juhl2010-10-291-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed two small issues in mac80211/debugfs_key.c::key_key_read while reading through the code. Patch below. The key_key_read() function returns ssize_t and the value that's actually returned is the return value of simple_read_from_buffer() which also returns ssize_t, so let's hold the return value in a ssize_t local variable rather than a int one. Also, memory is allocated dynamically with kmalloc() which can fail, but the return value of kmalloc() is not checked, so we may end up operating on a null pointer further on. So check for a NULL return and bail out with -ENOMEM in that case. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
