scsi: fcoe: Fix I/O path allocation

2020-08-18T01:52:39Z

ixgbe_fcoe_ddp_setup() can be called from the main I/O path and is called with a spin_lock held, so we have to use GFP_ATOMIC allocation instead of GFP_KERNEL.

net/intel: remove driver versions from Intel drivers

2020-06-26T05:25:13Z

As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

ixgbe: Use pci_get_dsn()

2020-03-06T01:36:46Z

Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The original code used a simple for-loop to read the bytes in order into a buffer one byte at a time. The pci_get_dsn() function returns the DSN as a u64, correctly ordering the upper and lower 32 bit dwords. Simplify the display code by using %016llX to display the u64 DSN. This should have equivalent behavior on both Little and Big Endian systems. The bus will have correctly ordered the dwords in the CPU endian format, while pci_get_dsn() will correctly order the lower and higher dwords into a u64.

ixgbe: Replace GFP_ATOMIC with GFP_KERNEL

2018-08-24T15:52:35Z

ixgbe_fcoe_ddp_setup(), ixgbe_setup_fcoe_ddp_resources() and ixgbe_sw_init() are never called in atomic context. They call kmalloc(), dma_pool_alloc() and kzalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai Acked-by: Sebastian Basierski Signed-off-by: Jeff Kirsher

net: intel: Cleanup the copyright/license headers

2018-04-27T18:00:04Z

After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

networking: make skb_put & friends return void pointers

2017-06-16T15:48:39Z

It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: Johannes Berg Signed-off-by: David S. Miller
