[PATCH RESEND v3 00/26] Add definition for the number of standard PCI BARs

Code that iterates over all standard PCI BARs typically uses PCI_STD_RESOURCE_END, but this is error-prone because it requires "i <= PCI_STD_RESOURCE_END" rather than something like "i < PCI_STD_NUM_BARS". We could add such a definition and use it the same way PCI_SRIOV_NUM_BARS is used. The

[PATCH] staging: rtl8723bs: Variable rf_type in function rtw_cfg80211_init_wiphy() could be uninitialized

In function rtw_cfg80211_init_wiphy(), local variable "rf_type" could be uninitialized if function rtw_hal_get_hwreg() fails to initialize it. However, this value is used in function rtw_cfg80211_init_ht_capab() and used to decide the value writing to ht_cap, which is potentially unsafe.

[PATCH] staging: rtl8188eu: fix null dereference when kzalloc fails

If kzalloc() returns NULL, the error path doesn't stop the flow of control from entering rtw_hal_read_chip_version() which dereferences the null pointer. Fix this by adding a 'goto' to the error path to more gracefully handle the issue and avoid proceeding with initialization steps that we're no

[PATCH v2 08/17] staging: qlge: Deduplicate rx buffer queue management

The qlge driver (and device) uses two kinds of buffers for reception, so-called "small buffers" and "large buffers". The two are arranged in rings, the sbq and lbq. These two share similar data structures and code. Factor out data structures into a common struct qlge_bq, make required adjustments

[PATCH v2 16/17] staging: qlge: Refill rx buffers up to multiple of 16

Reading the {s,l}bq_prod_idx registers on a running device, it appears that the adapter will only use buffers up to prod_idx & 0xfff0. The driver currently uses fixed-size guard zones (16 for sbq, 32 for lbq - don't know why this difference). After the previous patch, this approach no longer

[PATCH v2 15/17] staging: qlge: Update buffer queue prod index despite oom

Currently, if we repeatedly fail to allocate all of the buffers from the desired batching budget, we will never update the prod_idx register. Restructure code to always update prod_idx if new buffers could be allocated. This eliminates the current two stage process (clean_idx -> prod_idx) and some

[PATCH v2 02/17] staging: qlge: Remove irq_cnt

qlge uses an irq enable/disable refcounting scheme that is: * poorly implemented Uses a spin_lock to protect accesses to the irq_cnt atomic variable. * buggy Breaks when there is not a 1:1 sequence of irq - napi_poll, such as when using SO_BUSY_POLL. * unnecessary

[PATCH v2 09/17] staging: qlge: Fix dma_sync_single calls

lbq_buf_size is duplicated to every rx_ring structure whereas lbq_buf_order is present once in the ql_adapter structure. All rings use the same buf size, keep only one copy of it. Also factor out the calculation of lbq_buf_size instead of having two copies. Signed-off-by: Benjamin Poirier

[PATCH v2 17/17] staging: qlge: Refill empty buffer queues from wq

When operating at mtu 9000, qlge does order-1 allocations for rx buffers in atomic context. This is especially unreliable when free memory is low or fragmented. Add an approach similar to commit 3161e453e496 ("virtio: net refill on out-of-memory") to qlge so that the device doesn't lock up if

[PATCH v2 0/17] staging: qlge: Fix rx stall in case of allocation failures

qlge refills rx buffers from napi context. In case of allocation failure, allocation will be retried the next time napi runs. If a receive queue runs out of free buffers (possibly after subsequent allocation failures), it drops all traffic, no longer raises interrupts and napi is no longer

[PATCH v2 01/17] staging: qlge: Fix irq masking in INTx mode
