2018-09-12rds: fix two RCU related problemsCong Wang1-1/+4
When a rds sock is bound, it is inserted into the bind_hash_table which is protected by RCU. But when releasing rds sock, after it is removed from this hash table, it is freed immediately without respecting RCU grace period. This could cause some use-after-free as reported by syzbot. Mark the rds sock with SOCK_RCU_FREE before inserting it into the bind_hash_table, so that it would be always freed after a RCU grace period. The other problem is in rds_find_bound(), the rds sock could be freed in between rhashtable_lookup_fast() and rds_sock_addref(), so we need to extend RCU read lock protection in rds_find_bound() to close this race condition.

2018-09-12r8169: Clear RTL_FLAG_TASK_*_PENDING when clearing RTL_FLAG_TASK_ENABLEDKai-Heng Feng1-3/+6
After system suspend, sometimes the r8169 doesn't work when ethernet cable gets pluggued. This issue happens because rtl_reset_work() doesn't get called from rtl8169_runtime_resume(), after system suspend. In rtl_task(), RTL_FLAG_TASK_* only gets cleared if this condition is met: if (!netif_running(dev) || !test_bit(RTL_FLAG_TASK_ENABLED, tp->wk.flags)) ... If RTL_FLAG_TASK_ENABLED was cleared during system suspend while RTL_FLAG_TASK_RESET_PENDING was set, the next rtl_schedule_task() won't schedule task as the flag is still there. So in addition to clearing RTL_FLAG_TASK_ENABLED, also clears other flags.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for you net tree: 1) Remove duplicated include at the end of UDP conntrack, from Yue Haibing. 2) Restore conntrack dependency on xt_cluster, from Martin Willi. 3) Fix splat with GSO skbs from the checksum target, from Florian Westphal. 4) Rework ct timeout support, the template strategy to attach custom timeouts is not correct since it will not work in conjunction with conntrack zones and we have a possible free after use when removing the rule due to missing refcounting. To fix these problems, do not use conntrack template at all and set custom timeout on the already valid conntrack object. This fix comes with a preparation patch to simplify timeout adjustment by initializating the first position of the timeout array for all of the existing trackers. Patchset from Florian Westphal. 5) Fix missing dependency on from IPv4 chain NAT type, from Florian. 6) Release chain reference counter from the flush path, from Taehee Yoo. 7) After flushing an iptables ruleset, conntrack hooks are unregistered and entries are left stale to be cleaned up by the timeout garbage collector. No TCP tracking is done on established flows by this time. If ruleset is reloaded, then hooks are registered again and TCP tracking is restored, which considers packets to be invalid. Clear window tracking to exercise TCP flow pickup from the middle given that history is lost for us. Again from Florian. 8) Fix crash from netlink interface with CONFIG_NF_CONNTRACK_TIMEOUT=y and CONFIG_NF_CT_NETLINK_TIMEOUT=n. 9) Broken CT target due to returning incorrect type from ctnl_timeout_find_get(). 10) Solve conntrack clash on NF_REPEAT verdicts too, from Michal Vaner. 11) Missing conversion of hashlimit sysctl interface to new API, from Cong Wang. ==================== Signed-off-by: David S.

2018-09-11netfilter: conntrack: reset tcp maxwin on re-registerFlorian Westphal1-0/+26
Doug Smythies says: Sometimes it is desirable to temporarily disable, or clear, the iptables rule set on a computer being controlled via a secure shell session (SSH). While unwise on an internet facing computer, I also do it often on non-internet accessible computers while testing. Recently, this has become problematic, with the SSH session being dropped upon re-load of the rule set. The problem is that when all rules are deleted, conntrack hooks get unregistered. In case the rules are re-added later, its possible that tcp window has moved far enough so that all packets are considered invalid (out of window) until entry expires (which can take forever, default established timeout is 5 days). Fix this by clearing maxwin of existing tcp connections on register. v2: don't touch entries on hook removal. v3: remove obsolete expiry check.

2018-09-10qmi_wwan: Support dynamic config on Quectel EP06Kristian Evensen1-1/+29
Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB interfaces, without the device changing VID/PID or configuration number. When the configuration is updated and interfaces are added/removed, the interface numbers change. This means that the current code for matching EP06 does not work. This patch removes the current EP06 interface number match, and replaces it with a match on class, subclass and protocol. Unfortunately, matching on those three alone is not enough, as the diag interface exports the same values as QMI. The other serial interfaces + adb export different values and do not match. The diag interface only has two endpoints, while the QMI interface has three. I have therefore added a check for number of interfaces, and we ignore the interface if the number of endpoints equals two.

2018-09-09net/tls: Set count of SG entries if sk_alloc_sg returns -ENOSPCVakul Garg1-0/+6
tls_sw_sendmsg() allocates plaintext and encrypted SG entries using function sk_alloc_sg(). In case the number of SG entries hit MAX_SKB_FRAGS, sk_alloc_sg() returns -ENOSPC and sets the variable for current SG index to '0'. This leads to calling of function tls_push_record() with 'sg_encrypted_num_elem = 0' and later causes kernel crash. To fix this, set the number of SG elements to the number of elements in plaintext/encrypted SG arrays in case sk_alloc_sg() returns -ENOSPC.

2018-09-09net: ena: fix device destruction to gracefully free resourcesNetanel Belgazal1-6/+7
When ena_destroy_device() is called from ena_suspend(), the device is still reachable from the driver. Therefore, the driver can send a command to the device to free all resources. However, in all other cases of calling ena_destroy_device(), the device is potentially in an error state and unreachable from the driver. In these cases the driver must not send commands to the device. The current implementation does not request resource freeing from the device even when possible. We add the graceful parameter to ena_destroy_device() to enable resource freeing when possible, and use it in ena_suspend().

2018-09-09net: ena: fix driver when PAGE_SIZE == 64kBNetanel Belgazal2-5/+16
The buffer length field in the ena rx descriptor is 16 bit, and the current driver passes a full page in each ena rx descriptor. When PAGE_SIZE equals 64kB or more, the buffer length field becomes zero. To solve this issue, limit the ena Rx descriptor to use 16kB even when allocating 64kB kernel pages. This change would not impact ena device functionality, as 16kB is still larger than maximum MTU. Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S.

2018-09-09kbuild: modules_install: warn when missing System.map fileRandy Dunlap1-0/+1
If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.
