| In the Linux kernel, the following vulnerability has been resolved:
idpf: convert workqueues to unbound
When a workqueue is created with `WQ_UNBOUND`, its work items are
served by special worker-pools, whose host workers are not bound to
any specific CPU. In the default configuration (i.e. when
`queue_delayed_work` and friends do not specify which CPU to run the
work item on), `WQ_UNBOUND` allows the work item to be executed on any
CPU in the same node of the CPU it was enqueued on. While this
solution potentially sacrifices locality, it avoids contention with
other processes that might dominate the CPU time of the processor the
work item was scheduled on.
This is not just a theoretical problem: in a particular scenario
misconfigured process was hogging most of the time from CPU0, leaving
less than 0.5% of its CPU time to the kworker. The IDPF workqueues
that were using the kworker on CPU0 suffered large completion delays
as a result, causing performance degradation, timeouts and eventual
system crash.
* I have also run a manual test to gauge the performance
improvement. The test consists of an antagonist process
(`./stress --cpu 2`) consuming as much of CPU 0 as possible. This
process is run under `taskset 01` to bind it to CPU0, and its
priority is changed with `chrt -pQ 9900 10000 ${pid}` and
`renice -n -20 ${pid}` after start.
Then, the IDPF driver is forced to prefer CPU0 by editing all calls
to `queue_delayed_work`, `mod_delayed_work`, etc... to use CPU 0.
Finally, `ktraces` for the workqueue events are collected.
Without the current patch, the antagonist process can force
arbitrary delays between `workqueue_queue_work` and
`workqueue_execute_start`, that in my tests were as high as
`30ms`. With the current patch applied, the workqueue can be
migrated to another unloaded CPU in the same node, and, keeping
everything else equal, the maximum delay I could see was `6us`. |
| A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. |
| Serv-U web login screen to LDAP authentication was allowing characters that were not sufficiently sanitized. SolarWinds has updated the input mechanism to perform additional validation and sanitization. Please Note: No downstream affect has been detected as the LDAP servers ignored improper characters. To insure proper input validation is completed in all environments. SolarWinds recommends scheduling an update to the latest version of Serv-U. |
| In the Linux kernel, the following vulnerability has been resolved:
ice: Fix memory corruption in VF driver
Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,
while VF still has queues configured, VF may unmap DMA resources.
In such scenario device still can map packets to memory, which ends up
silently corrupting it.
Previously, VF driver could experience memory corruption, which lead to
crash:
