If size is smaller than the lov_user_md struct then we are reading beyond the end of the buffer. I guess this is an information leak or it could cause an Oops if the memory is not mapped. Signed-off-by:

This is mostly to silence static checker complaints. In theory the problem here is that if size is in the 1-3 range then we don't allocate enough memory for the posix_acl_xattr_header struct and it results in memory corruption. But in reality kmalloc() return values are aligned at sizeof(long) so corrupting this small amount of data is not harmful. The "size" variable should be type size_t. The value of size is checked in setxattr() so we know it is a number between "0 - XATTR_SIZE_MAX". There is no need to check for negative sizes. Signed-off-by:

Static checkers warn that if cfs_cpt_table_print() returns an error other than -EFBIG, then it would lead to a double free. This is true but cfs_cpt_table_print() only returns -EFBIG on error so it also won't happen in real life. Signed-off-by:

Old version of lustre (1.8) calculated RPC checksums differently, but the compat code is no longer important since in-kernel version of lustre is nto compatible with 1.8 lustre servers (that are long deprecated too). Signed-off-by:

Given that this code is now part of the kernel tree, the #ifdef directive comparing LUSTRE_VERSION_CODE to the kernel version is no longer needed. As a side effect, this will also remove the sparse error "directive in argument list". Signed-off-by:

Commit 24051247 ("staging: comedi: comedi_test: use comedi_handle_events()") resulted in the timer routine `waveform_ai_interrupt()` calling `comedi_handle_events()` instead of `comedi_events()`. That had the advantage of automatically stopping the acquisition on overflow/error/end-of-acquisition conditions (by calling the comedi subdevice's "cancel" handler), but currently results in the timer routine locking when one of those conditions occur. This is because the "cancel" handler `waveform_ai_cancel()` calls `del_timer_sync()`. Fix it by adding a bit to the device private data that indicates whether the acquisition is active or not, and changing the "cancel" handler to use `del_timer()` instead of `del_timer_sync()`. The bit is set when starting the acquisition, cleared when ending the acquisition (in the "cancel" handler), and tested in the timer routine, which will do nothing if the acquisition is inactive. Also, make sure any scheduled timeout event gets cancelled when the low-level device gets "detached" from the comedi core by calling `del_timer_sync()` in the "detach" handler `waveform_detach()`.

Introduce a few static inline helper functions: `comedi_bytes_per_sample(s)` is the same as the existing `bytes_per_sample(s)` and determines the size of a comedi sample in bytes. (`bytes_per_sample(s)` will be removed.) `comedi_sample_shift(s)` determines the log2 of the comedi sample size, so it can be used in bit-shift operations to multiply or divide by the sample size. `comedi_bytes_to_samples(s, nbytes)` converts a number of bytes to a number of samples (rounding down). `comedi_samples_to_bytes(s, nsamples)` converts a number of samples to a number of bytes.

This driver currently passes the timer channel as the data[5] element to the timer (*insn_config) function. This is stored in the private data and use in the timer (*insn_read) and (*insn_write) functions to read/write the timer. This is just wrong, comedi passes the channel number in the insn->chanspec. Use that instead and remove the private data member. Signed-off-by:

According to ADDI-DATA, the APCI-1564 only has 3 timers. There are some customer specific boards with 4 timers but they use out of tree drivers. Now that the timer 'channels' are handled correctly in the subdevice functions, fix the number of timer channels for the subdevice and remove the code that would access a 4th timer. Also, remove the unnecessary initialzation of the subdevice 'len_chanlist'. That member is only used by subdevices that support async commands. Signed-off-by:

The dev->read_subdev used in this driver for async commands returns 32-bit samples and should have the SDF_LSAMPL subdev_flag set. It also returns the full scan with each sample so it should have the SDF_PACKED subdev_flag set. Add the missing subdev_flags and use comedi_buf_write_samples() to add the sample to the async buffer. The COMEDI_CB_BLOCK and COMEDI_CB_EOS events will be automatically handled by the core. Remove the unnecessary events in the driver. Signed-off-by:

Use comedi_buf_write_samples() to add the sample to the async buffer. The 32-bit sample size is automatically determined due to the subddev_flag SDF_LSAMPL. The async event COMEDI_CB_BLOCK will be automatically set by the core. Remove the unnecessary event in the driver. This driver also has the SDF_PACKED subdev_flag set so the core will automatically set the COMEDI_CB_EOS event after adding the sample. Signed-off-by:

Add the missing subdev_flags and use comedi_buf_write_samples() to add the sample to the async buffer. The async events will set properly by the core. A dev_warn() message will also be output by the core if the buffer overflows. Remove the unnecessary events and dev_err() message in the driver. Signed-off-by:
