perf evsel: Separate bpf_counter_list and bpf_filters, can be used at the same time
'struct evsel' uses a union for the two lists. This turned out to be
error prone.
For example:
[root@quaco ~]# perf stat --bpf-prog 5246
Error: cpu-clock event does not have sample flags 66c660
failed to set filter "(null)" on event cpu-clock with 2 (No such file or directory)
[root@quaco ~]# perf stat --bpf-prog 5246
Fix this issue by separating the two lists.

mtd: spi-nor: Fix divide by zero for spi-nor-generic flashes
We failed to initialize n_banks for spi-nor-generic flashes, which
caused a devide by zero when computing the bank_size.
By default we consider that all chips have a single bank. Initialize
the default number of banks for spi-nor-generic flashes. Even if the
bug is fixed with this simple initialization, check the n_banks value
before dividing so that we make sure this kind of bug won't occur again
if some other struct instance is created uninitialized.

amd-xgbe: fix the false linkup in xgbe_phy_status
In the event of a change in XGBE mode, the current auto-negotiation
needs to be reset and the AN cycle needs to be re-triggerred. However,
the current code ignores the return value of xgbe_set_mode(), leading to
false information as the link is declared without checking the status
register.
Fix this by propagating the mode switch status information to
xgbe_phy_status().

netrom: fix info-leak in nr_write_internal()
Simon Kapadia reported the following issue:
<quote>
The Online Amateur Radio Community (OARC) has recently been experimenting
with building a nationwide packet network in the UK.
As part of our experimentation, we have been testing out packet on 300bps HF,
and playing with net/rom. For HF packet at this baud rate you really need
to make sure that your MTU is relatively low; AX.25 suggests a PACLEN of 60,
and a net/rom PACLEN of 40 to go with that.
However the Linux net/rom support didn't work with a low PACLEN;
the mkiss module would truncate packets if you set the PACLEN below about 200 or so, e.g.:
Apr 19 14:00:51 radio kernel: [12985.747310] mkiss: ax1: truncating oversized transmit packet!
This didn't make any sense to me (if the packets are smaller why would they
be truncated?) so I started investigating.
I looked at the packets using ethereal, and found that many were just huge
compared to what I would expect.
A simple net/rom connection request packet had the request and then a bunch
of what appeared to be random data following it:
</quote>
Simon provided a patch that I slightly revised:
Not only we must not use skb_tailroom(), we also do
not want to count NR_NETWORK_LEN twice.

net: stmmac: fix call trace when stmmac_xdp_xmit() is invoked
We encountered a kernel call trace issue which was related to
ndo_xdp_xmit callback on our i.MX8MP platform. The reproduce
steps show as follows.
1. The FEC port (eth0) connects to a PC port, and the PC uses
pktgen_sample03_burst_single_flow.sh to generate packets and
send these packets to the FEC port. Notice that the script must
be executed before step 2.
2. Run the "./xdp_redirect eth0 eth1" command on i.MX8MP, the
eth1 interface is the dwmac. Then there will be a call trace
issue soon. Please see the log for more details.
The root cause is that the NETDEV_XDP_ACT_NDO_XMIT feature is
enabled by default, so when the step 2 command is exexcuted
and packets have already been sent to eth0, the stmmac_xdp_xmit()
starts running before the stmmac_xdp_set_prog() finishes. To
resolve this issue, we disable the NETDEV_XDP_ACT_NDO_XMIT
feature by default and turn on/off this feature when the bpf
program is installed/uninstalled which just like the other
ethernet drivers.

smb3: missing null check in SMB2_change_notify
If plen is null when passed in, we only checked for null in one of the two places where it could be used. Although plen is always valid (not null) for current callers of the SMB2_change_notify function, this change makes it more consistent.

module: error out early on concurrent load of the same module file
It turns out that udev under certain circumstances will concurrently try
to load the same modules over-and-over excessively. This isn't a kernel
bug, but it ends up affecting the kernel, to the point that under
certain circumstances we can fail to boot, because the kernel uses a lot
of memory to read all the module data all at once.
Note that it isn't a memory leak, it's just basically a thundering herd
problem happening at bootup with a lot of CPUs, with the worst cases
then being pretty bad.
Admittedly the worst situations are somewhat contrived: lots and lots of
CPUs, not a lot of memory, and KASAN enabled to make it all slower and
as such (unintentionally) exacerbate the problem.
Luis explains: [1]
"My best assessment of the situation is that each CPU in udev ends up
triggering a load of duplicate set of modules, not just one, but *a
lot*. Not sure what heuristics udev uses to load a set of modules per
CPU."
Petr Pavlu chimes in: [2]
"My understanding is that udev workers are forked. An initial kmod
context is created by the main udevd process but no sharing happens
after the fork. It means that the mentioned memory pool logic doesn't
really kick in.
Multiple parallel load requests come from multiple udev workers, for
instance, each handling an udev event for one CPU device and making
the exactly same requests as all others are doing at the same time.
The optimization idea would be to recognize these duplicate requests
at the udevd/kmod level and converge them"
Note that module loading has tried to mitigate this issue before, see
for example commit

Pull vfs fixes from Christian Brauner:
- During the acl rework we merged this cycle the generic_listxattr()
helper had to be modified in a way that in principle it would allow
for POSIX ACLs to be reported. At least that was the impression we
had initially. Because before the acl rework POSIX ACLs would be
reported if the filesystem did have POSIX ACL xattr handlers in
sb->s_xattr. That logic changed and now we can simply check whether
the superblock has SB_POSIXACL set and if the inode has
inode->i_{default_}acl set report the appropriate POSIX ACL name.
However, we didn't realize that generic_listxattr() was only ever
used by two filesystems. Both of them don't support POSIX ACLs via
sb->s_xattr handlers and so never reported POSIX ACLs via
generic_listxattr() even if they raised SB_POSIXACL and did contain
inodes which had acls set. The example here is nfs4.
As a result, generic_listxattr() suddenly started reporting POSIX
ACLs when it wouldn't have before. Since SB_POSIXACL implies that the
umask isn't stripped in the VFS nfs4 can't just drop SB_POSIXACL from
the superblock as it would also alter umask handling for them.
So just have generic_listxattr() not report POSIX ACLs as it never
did anyway. It's documented as such.
- Our SB_* flags currently use a signed integer and we shift the last
bit causing UBSAN to complain about undefined behavior. Switch to
using unsigned. While the original patch used an explicit unsigned
bitshift it's now pretty common to rely on the BIT() macro in a lot
of headers nowadays. So the patch has been adjusted to use that.
- Add Namjae as ntfs reviewer. They're already active this cycle so
let's make it explicit right now.

x86/topology: Fix erroneous smp_num_siblings on Intel Hybrid platforms
Traditionally, all CPUs in a system have identical numbers of SMT siblings. That changes with hybrid processors where some logical CPUs have a sibling and others have none. Today, the CPU boot code sets the global variable smp_num_siblings when every CPU thread is brought up. The last thread to boot will overwrite it with the number of siblings of *that* thread. That last thread to boot will "win". If the thread is a Pcore, smp_num_siblings == 2. If it is an Ecore, smp_num_siblings == 1. smp_num_siblings describes if the *system* supports SMT. It should specify the maximum number of SMT threads among all cores. Ensure that smp_num_siblings represents the system-wide maximum number of siblings by always increasing its value. Never allow it to decrease. On MeteorLake-P platform, this fixes a problem that the Ecore CPUs are not updated in any cpu sibling map because the system is treated as an UP system when probing Ecore CPUs. Below shows part of the CPU topology information before and after the fix, for both Pcore and Ecore CPU (cpu0 is Pcore, cpu 12 is Ecore). ... -/sys/devices/system/cpu/cpu0/topology/package_cpus:000fff -/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-11 +/sys/devices/system/cpu/cpu0/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-21 ... -/sys/devices/system/cpu/cpu12/topology/package_cpus:001000 -/sys/devices/system/cpu/cpu12/topology/package_cpus_list:12 +/sys/devices/system/cpu/cpu12/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu12/topology/package_cpus_list:0-21 Notice that the "before" 'package_cpus_list' has only one CPU. This means that userspace tools like lscpu will see a little laptop like an 11-socket system: -Core(s) per socket: 1 -Socket(s): 11 +Core(s) per socket: 16 +Socket(s): 1 This is also expected to make the scheduler do rather wonky things too.

cpufreq: amd-pstate: Update policy->cur in amd_pstate_adjust_perf()
Driver should update policy->cur after updating the frequency.
Currently amd_pstate doesn't update policy->cur when `adjust_perf`
is used. Which causes /proc/cpuinfo to show wrong cpu frequency.
Fix this by updating policy->cur with correct frequency value in
adjust_perf function callback.
- Before the fix: (setting min freq to 1.5 MHz)
[root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
1 cpu MHz : 1777.016
1 cpu MHz : 1797.160
1 cpu MHz : 1797.270
189 cpu MHz : 400.000
- After the fix: (setting min freq to 1.5 MHz)
[root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
1 cpu MHz : 1753.353
1 cpu MHz : 1756.838

io_uring: unlock sqd->lock before sq thread release CPU
The sq thread actively releases CPU resources by calling the cond_resched() and schedule() interfaces when it is idle. Therefore, more resources are available for other threads to run. There exists a problem in sq thread: it does not unlock sqd->lock before releasing CPU resources every time. This makes other threads pending on sqd->lock for a long time. For example, the following interfaces all require sqd->lock: io_sq_offload_create(), io_register_iowq_max_workers() and io_ring_exit_work(). Before the sq thread releases CPU resources, unlocking sqd->lock will provide the user a better experience because it can respond quickly to user requests.

MAINTAINERS: update arm64 Microchip entries
Krzysztof noticed that patches for arch/arm64/boot/dts/microchip were getting lost & the listed tree was inactive. Nicolas and I are willing to shepherd patches to Arnd, using the existing at91 tree, so add a new entry covering arch/arm64/boot/dts/microchip, listing us as maintainers. Drop the tree from the existing sparx5 entry & narrow the devicetree pattern to just sparx devices, leaving Lars, Steen and Daniel looking after support for their SoCs.

efi: fix missing prototype warnings

efi/libstub: zboot: Avoid eager evaluation of objcopy flags
The Make variable containing the objcopy flags may be constructed from the output of build tools operating on build artifacts, and these may not exist when doing a make clean. So avoid evaluating them eagerly, to prevent spurious build warnings.

Merge branch 'net-phy-mscc-support-vsc8501'
David Epping says: ==================== net: phy: mscc: support VSC8501 this updated series of patches adds support for the VSC8501 Ethernet PHY and fixes support for the VSC8502 PHY in cases where no other software (like U-Boot) has initialized the PHY after power up. The first patch simply adds the VSC8502 to the MODULE_DEVICE_TABLE, where I guess it was unintentionally missing. I have no hardware to test my change. The second patch adds the VSC8501 PHY with exactly the same driver implementation as the existing VSC8502. The (new) third patch removes phydev locking from vsc85xx_rgmii_set_skews(), as discussed for v2 of the patch set. The (now) fourth patch fixes the initialization for VSC8501 and VSC8502. I have tested this patch with VSC8501 on hardware in RGMII mode only. https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DataSheets/VSC8501-03_Datasheet_60001741A.PDF https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DataSheets/VSC8502-03_Datasheet_60001742B.pdf Table 4-42 "RGMII CONTROL, ADDRESS 20E2 (0X14)" Bit 11 for each of them. By default the RX_CLK is disabled for these PHYs. In cases where no other software, like U-Boot, enabled the clock, this results in no received packets being handed to the MAC. The patch enables this clock output. According to Microchip support (case number 01268776) this applies to all modes (RGMII, GMII, and MII). Other PHYs sharing the same register map and code, like VSC8530/31/40/41 have the clock enabled and the relevant bit 11 is reserved and read-only for them. As per previous discussion the patch still clears the bit on these PHYs, too, possibly more easily supporting other future PHYs implementing this functionality. For the VSC8572 family of PHYs, having a different register map, no such changes are applied. ==================== Link: https://lore.kernel.org/r/20230523153108.18548-1-david.epping@missinglinkelectronics.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
