2023-06-23net: hns3: clear hns unused parameter alarmPeiyang Wang

2023-06-23net: hns3: fix strncpy() not using dest-buf length as length issueHao Chen
Now, strncpy() in hns3_dbg_fill_content() use src-length as copy-length, it may result in dest-buf overflow. This patch is to fix intel compile warning for csky-linux-gcc (GCC) 12.1.0 compiler. The warning reports as below: hclge_debugfs.c:92:25: warning: 'strncpy' specified bound depends on the length of the source argument [-Wstringop-truncation] strncpy(pos, items[i].name, strlen(items[i].name)); hclge_debugfs.c:90:25: warning: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation] strncpy(pos, result[i], strlen(result[i])); strncpy() use src-length as copy-length, it may result in dest-buf overflow. So,this patch add some values check to avoid this issue.

2023-06-23hwrng: st - keep clock enabled while hwrng is registeredMartin Kaiser
The st-rng driver uses devres to register itself with the hwrng core, the driver will be unregistered from hwrng when its device goes out of scope. This happens after the driver's remove function is called. However, st-rng's clock is disabled in the remove function. There's a short timeframe where st-rng is still registered with the hwrng core although its clock is disabled. I suppose the clock must be active to access the hardware and serve requests from the hwrng core. Switch to devm_clk_get_enabled and let devres disable the clock and unregister the hwrng. This avoids the race condition.

2023-06-23crypto: sig - Add interface for sign/verifyHerbert Xu
Split out the sign/verify functionality from the existing akcipher interface. Most algorithms in akcipher either support encryption and decryption, or signing and verify. Only one supports both. As a signature algorithm may not support encryption at all, these two should be spearated. For now sig is simply a wrapper around akcipher as all algorithms remain unchanged. This is a first step and allows users to start allocating sig instead of akcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2023-06-23crypto: caam - optimize RNG sample sizeMeenakshi Aggarwal
TRNG "sample size" (the total number of entropy samples that will be taken during entropy generation) default / POR value is very conservatively set to 2500. Let's set it to 512, the same as the caam driver in U-boot (drivers/crypto/fsl_caam.c) does. This solves the issue of RNG performance dropping after a suspend/resume cycle on parts where caam loses power, since the initial U-boot setttings are lost and kernel does not restore them when resuming. Note: when changing the sample size, the self-test parameters need to be updated accordingly.

There are situations during the xhci_resume() sequence, which allows for re-initializing of the XHCI HC. However, in case the HCD is being removed, these operations may not be needed. Set the removal state before issuing the runtime PM get on the XHCI device, so that the XHCI resume routine will know when to bypass the re-init logic.

2023-06-23usb: host: xhci: Do not re-initialize the XHCI HC if being removedWesley Cheng
During XHCI resume, if there was a host controller error detected the routine will attempt to re-initialize the XHCI HC, so that it can return back to an operational state. If the XHCI host controller is being removed, this sequence would be already handled within the XHCI halt path, leading to a duplicate set of reg ops/calls. In addition, since the XHCI bus is being removed, the overhead added in restarting the HCD is unnecessary. Check for the XHC state before setting the reinit_xhc parameter, which is responsible for triggering the restart.

2023-06-23usbip: usbip_host: Replace strlcpy with strscpyAzeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of sizeof(dest).

2023-06-23usb: dwc3: gadget: Propagate core init errors to UDC during pullupKrishna Kurapati
In scenarios where pullup relies on resume (get sync) to initialize the controller and set the run stop bit, then core_init is followed by gadget_resume which will eventually set run stop bit. But in cases where the core_init fails, the return value is not sent back to udc appropriately. So according to UDC the controller has started but in reality we never set the run stop bit. On systems like Android, there are uevents sent to HAL depending on whether the configfs_bind / configfs_disconnect were invoked. In the above mentioned scnenario, if the core init fails, the run stop won't be set and the cable plug-out won't result in generation of any disconnect event and userspace would never get any uevent regarding cable plug out and we never call pullup(0) again. Furthermore none of the next Plug-In/Plug-Out's would be known to configfs. Return back the appropriate result to UDC to let the userspace/ configfs know that the pullup failed so they can take appropriate action.
