* netfilter: avoid race with exp->master ctJesper Dangaard Brouer2014-03-072-1/+15
| | | | | | | | | | | | | | | | | | | | Preparation for disconnecting the nf_conntrack_lock from the expectations code. Once the nf_conntrack_lock is lifted, a race condition is exposed. The expectations master conntrack exp->master, can race with delete operations, as the refcnt increment happens too late in init_conntrack(). Race is against other CPUs invoking ->destroy() (destroy_conntrack()), or nf_ct_delete() (via timeout or early_drop()). Avoid this race in nf_ct_find_expectation() by using atomic_inc_not_zero(), and checking if nf_ct_is_dying() (path via nf_ct_delete()).

* netfilter: conntrack: spinlock per cpu to protect special lists.Jesper Dangaard Brouer2014-03-075-79/+168
| | | | | | | | | | | | | One spinlock per cpu to protect dying/unconfirmed/template special lists. (These lists are now per cpu, a bit like the untracked ct) Add a @cpu field to nf_conn, to make sure we hold the appropriate spinlock at removal time.

* | netfilter: ipset: add forceadd kernel support for hash set typesJosh Hunt2014-03-0614-12/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new property for hash set types, where if a set is created with the 'forceadd' option and the set becomes full the next addition to the set may succeed and evict a random entry from the set. To keep overhead low eviction is done very simply. It checks to see which bucket the new entry would be added. If the bucket's pos value is non-zero (meaning there's at least one entry in the bucket) it replaces the first entry in the bucket. If pos is zero, then it continues down the normal add process. This property is useful if you have a set for 'ban' lists where it may not matter if you release some entries from the set early.

* | netfilter: ipset: kernel: uapi: fix MARKMASK attr ABI breakageFlorian Westphal2014-03-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2dfb973c0dcc6d2211 (add markmask for hash:ip,mark data type) inserted IPSET_ATTR_MARKMASK in-between other enum values, i.e. changing values of all further attributes. This causes 'ipset list' segfault on existing kernels since ipset no longer finds IPSET_ATTR_MEMSIZE (it has a different value on kernel side). Jozsef points out it should be moved below IPSET_ATTR_MARK which works since there is some extra reserved space after that value.

This includes userspace and kernelspace code, hash:ip,mark set tests and man page updates. The intended use of ip,mark set is similar to the ip:port type, but for protocols which don't use a predictable port number. Instead of port number it matches a firewall mark determined by a layer 7 filtering program like opendpi. As well as allowing or blocking traffic it will also be used for accounting packets and bytes sent for each protocol. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>

* | netfilter: ipset: Follow manual page behavior for SET target on list:setSergey Popovich2014-03-061-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipset(8) for list:set says: The match will try to find a matching entry in the sets and the target will try to add an entry to the first set to which it can be added. However real behavior is bit differ from described. Consider example: # ipset create test-1-v4 hash:ip family inet # ipset create test-1-v6 hash:ip family inet6 # ipset create test-1 list:set # ipset add test-1 test-1-v4 # ipset add test-1 test-1-v6 # iptables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src # ip6tables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src And then when iptables/ip6tables rule matches packet IPSET target tries to add src from packet to the list:set test-1 where first entry is test-1-v4 and the second one is test-1-v6. For IPv4, as it first entry in test-1 src added to test-1-v4 correctly, but for IPv6 src not added! Placing test-1-v6 to the first element of list:set makes behavior correct for IPv6, but brokes for IPv4. This is due to result, returned from ip_set_add() and ip_set_del() from net/netfilter/ipset/ip_set_core.c when set in list:set equires more parameters than given or address families do not match (which is this case). It seems wrong returning 0 from ip_set_add() and ip_set_del() in this case, as 0 should be returned only when an element successfuly added/deleted to/from the set, contrary to ip_set_test() which returns 0 when no entry exists and >0 when entry found in set.

* netfilter: nf_tables: add optional user data area to rulesPablo Neira Ayuso2014-02-273-5/+28

Scratch 8 bits for the new ulen field that indicates the length the user data area. 4 bits from the handle (so it's 42 bits long, according to Patrick, it would last 139 years with 1000 new rules per second) and 4 bits from dlen (so the expression data area is 4K, which seems sufficient by now even considering the compatibility layer).

Also removes a useless run-time check: words cannot grow beyond 4 (32 bit) or 2 (64bit) since xt_connlabel enforces a maximum of 128 labels.

| | | * | drm: add DRM_CAPs for cursor sizeAlex Deucher2014-02-183-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hardware may not support standard 64x64 cursors. Add a drm cap to query the cursor size from the kernel. Some examples include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32). This allows things like device specific ddxes to remove asics specific logic and also allows xf86-video-modesetting to work properly with hw cursors on this hardware. Default to 64 if the driver doesn't specify a size. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Rob Clark <robdclark@gmail.com>

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were already storing the bpc (bits per color) information in radeon_crtc, so just use that everywhere rather than calculating it everywhere we use it. This also allows us to change it in one place if we ever want to override it. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

However mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the untiled check to explicitly include all pre-nv50 cards.
