Call eth_random_addr to generate a random mac address if we cannot load the mac address from the efuses. Do not use a constant mac address as fallback. This may create conflicts if we have several r8188eu devices on the network. Suggested-by:

Use kmalloc to allocate the efuse buffer in ReadAdapterInfo8188EU and free it on exit. This is better than using a 512 byte array on the stack. It's ok to drop the __aligned(4) qualifier. kmalloc aligns to ARCH_KMALLOC_MINALIGN, this is at least 8 bytes. Suggested-by:

If BOOT_FROM_EEPROM is set, efuse_buf is not initialised before it is passed to functions that read from it. The buffer will be filled with 0x00 in this case like all local variables. However, the parsing functions expect the buffer to be filled with 0xFF if reading eeprom/efuse data failed. Fill the buffer with 0xFF before we try to read the data. Please note that this problem existed before we started using a local buffer. Adapter->eeprompriv->efuse_eeprom_data was allocated as a part of struct adapter by a vzalloc call in rtw_usb_if1_init.

The efuse_eeprom_data array in struct eeprom_priv is used only by ReadAdapterInfo8188EU. We can remove efuse_eeprom_data and use a local buffer instead. Use EFUSE_MAP_LEN_88E as buffer size. Its value is the same as HWSET_MAX_SIZE_512. The functions that access the buffer use EFUSE_MAP_LEN_88E for its size. Signed-off-by:

The EepromOrEfuse flag in struct eeprom_priv is used only in the ReadAdapterInfo8188EU function. We can remove EepromOrEfuse from struct eeprom_priv. As the meaning of EepromOrEfuse isn't obvious, there is a macro is_boot_from_eeprom that's used for checking the value. We don't need the macro, writing the check as !(eeValue & BOOT_FROM_EEPROM) makes it clear what is checked. Signed-off-by:

There are sleep in atomic context bugs when dm_fsync_timer_callback is executing. The root cause is that the memory allocation functions with GFP_KERNEL or GFP_NOIO parameters are called in dm_fsync_timer_callback which is a timer handler. The call paths that could trigger bugs are shown below: (interrupt context) dm_fsync_timer_callback write_nic_byte kzalloc(sizeof(data), GFP_KERNEL); //may sleep usb_control_msg kmalloc(.., GFP_NOIO); //may sleep write_nic_dword kzalloc(sizeof(data), GFP_KERNEL); //may sleep usb_control_msg kmalloc(.., GFP_NOIO); //may sleep This patch uses delayed work to replace timer and moves the operations that may sleep into the delayed work in order to mitigate bugs.

This is a collection of three fixes for small annoyances. Two of these are already pending in other trees, but I really don't want to release another -rc with these issues pending, so I picked up the patches for these things directly. We'll end up with duplicate commits eventually, I prefer that over having these issues pending. The third one is just me getting rid of another BUG_ON() just because it was reported and I dislike those things so much. * merge 'hot-fixes' branch: ida: don't use BUG_ON() for debugging drm/aperture: Run fbdev removal before internal helpers ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()

This is another old BUG_ON() that just shouldn't exist (see also commit a382f8fe: "signal handling: don't use BUG_ON() for debugging"). In fact, as Matthew Wilcox points out, this condition shouldn't really even result in a warning, since a negative id allocation result is just a normal allocation failure: "I wonder if we should even warn here -- sure, the caller is trying to free something that wasn't allocated, but we don't warn for kfree(NULL)" and goes on to point out how that current error check is only causing people to unnecessarily do their own index range checking before freeing it. This was noted by Itay Iellin, because the bluetooth HCI socket cookie code does *not* do that range checking, and ends up just freeing the error case too, triggering the BUG_ON(). The HCI code requires CAP_NET_RAW, and seems to just result in an ugly splat, but there really is no reason to BUG_ON() here, and we have generally striven for allocation models where it's always ok to just do free(alloc()); even if the allocation were to fail for some random reason (usually obviously that "random" reason being some resource limit). Fixes: 88eca020 ("ida: simplified functions for id allocation") Reported-by:
