2010-02-16CAPI: Rework capi_ctr_ready/downJan Kiszka1-45/+50
This step prepares the application of proper controller locking: Push all state changing work into the notify handler that are called by capi_ctr_ready and capi_ctr_down, switch detach_capi_ctr to issue a synchronous ctr_down. Also ensure that we do not go through any action if the state did not change. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Convert capi drivers rwlock into mutexJan Kiszka3-32/+27

2010-02-16CAPI: Call a controller 'controller', not 'card'Jan Kiszka4-169/+178
At least for our internal use, fix the misnomers that refer to a CAPI controller as 'card'. No functional changes. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Reduce chattiness during module loading/removalJan Kiszka4-83/+9
The CVS revisions dumped by all CAPI modules are meaningless today. And that some CAPI module is loaded or removed does not necessarily deserve a message. Just keep the message of the central module, capi.ko, drop the rest. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Pin capifs instead of mounting itJan Kiszka1-9/+18
Auto-mounting the capifs during module init prevents unloading its module. Instead, pin the filesystem as long as some NCCI node exists. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-02-16CAPI: Sanitize capifs APIJan Kiszka3-31/+54
Instead of looking up the dentry of an NCCI node again in capifs_free_ncci pass the pointer via the capifs user. This patch also reduces the #ifdef mess in capi.c a bit as far as capifs was causing it. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Fix leaks in capifs_new_ncciJan Kiszka1-7/+18
When something went wrong during capifs_new_ncci, the looked up dentry was not properly released. Neither was the allocated inode. Refactor the function to avoid leaks. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16net neigh: Decouple per interface neighbour table controls from binary sysctlsEric W. Biederman7-13/+8
Stop computing the number of neighbour table settings we have by counting the number of binary sysctls. This behaviour was silly and meant that we could not add another neighbour table setting without also adding another binary sysctl. Don't pass the binary sysctl path for neighour table entries into neigh_sysctl_register. These parameters are no longer used and so are just dead code. Signed-off-by: Eric W.

2010-02-15net/macvtap: fix reference countingArnd Bergmann1-13/+22
The RCU usage in the original code was broken because there are cases where we possibly sleep with rcu_read_lock held. As a fix, change the macvtap_file_get_queue to get a reference on the socket and the netdev instead of taking the full rcu_read_lock. Also, change macvtap_file_get_queue failure case to not require a subsequent macvtap_file_put_queue, as pointed out by Ed Swierk.

2010-02-15netfilter: CONFIG_COMPAT: allow delta to exceed 32767Florian Westphal2-4/+4
with 32 bit userland and 64 bit kernels, it is unlikely but possible that insertion of new rules fails even tough there are only about 2000 iptables rules. This happens because the compat delta is using a short int. Easily reproducible via "iptables -m limit" ; after about 2050 rules inserting new ones fails with -ELOOP. Note that compat_delta included 2 bytes of padding on x86_64, so structure size remains the same. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Patrick McHardy <kaber@trash.net>

This will cause trouble once CONFIG_COMPAT support is added to ebtables. xt_compat_*_offset() calculate the kernel/userland structure size delta using: XT_ALIGN(size) - COMPAT_XT_ALIGN(size) If the match/target sizes are aligned at registration time, delta is always zero.
