2018-09-12net: ethernet: Fix up drivers masking pause supportAndrew Lunn1-2/+2
PHY drivers don't indicate they support pause. They expect MAC drivers to enable its support if the MAC has the needed hardware. Thus MAC drivers should not mask Pause support, but enable it.

Many Ethernet MAC drivers want to limit the PHY to only advertise a maximum speed of 100Mbs or 1Gbps. Rather than using a mask, make use of the helper function phy_set_max_speed().

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook1-2/+3
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-05-04tg3: Fix vunmap() BUG_ON() triggered from tg3_free_consistent().Michael Chan1-4/+5
tg3_free_consistent() calls dma_free_coherent() to free tp->hw_stats under spinlock and can trigger BUG_ON() in vunmap() because vunmap() may sleep. Fix it by removing the spinlock and relying on the TG3_FLAG_INIT_COMPLETE flag to prevent race conditions between tg3_get_stats64() and tg3_free_consistent(). TG3_FLAG_INIT_COMPLETE is always cleared under tp->lock before tg3_free_consistent() and therefore tg3_get_stats64() can safely access tp->hw_stats under tp->lock if TG3_FLAG_INIT_COMPLETE is set.

This fixes a hang issue seen when changing the MTU size from 1500 MTU to 9000 MTU on both 5717 and 5719 chips. In discussion with Broadcom, they've indicated that these chipsets have the same phy as the 57766 chipset, so the same workarounds apply. This has been tested by IBM on both Power 8 and Power 9 systems as well as by Broadcom on x86 hardware and has been confirmed to resolve the hang issue.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook1-3/+3
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

I found the zero Tx coalescing time stops generating interrupts for outgoing packets as well and fires Tx watchdog later. To avoid this, don't allow to set Tx coalescing time to 0 and also remove subsequent checks that become senseless.

2016-02-09tg3: Fix for tg3 transmit queue 0 timed out when too many gso_segsSiva Reddy Kallam1-6/+19
tg3_tso_bug() can hit a condition where the entire tx ring is not big enough to segment the GSO packet. For example, if MSS is very small, gso_segs can exceed the tx ring size. When we hit the condition, it will cause tx timeout. tg3_tso_bug() is called to handle TSO and DMA hardware bugs. For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet. For DMA bugs, we can still fall back to linearize the SKB and let the hardware transmit the TSO packet. This patch adds a function tg3_tso_bug_gso_check() to check if there are enough tx descriptors for GSO before calling tg3_tso_bug(). The caller will then handle the error appropriately - drop or lineraize the SKB. v2: Corrected patch description to avoid confusion.

When having permanent EEH error, the PCI device will be removed from the system. For this case, we shouldn't set pcierr_recovery to true wrongly, which blocks the driver to release the allocated interrupts and their handlers. Eventually, we can't disable MSI or MSIx successfully because of the MSI or MSIx interrupts still have associated interrupt actions, which is turned into following stack dump.
