2019-06-27backport-include: add empty lockdep_map structure in lockdep.hArend van Spriel
include/linux/rhashtable.h now uses struct lockdep_map unconditionally which is fine for upstream as lockdep.h defines an empty lockdep_map structure if CONFIG_LOCKDEP is not set. However, that is only true since kernel 4.15 so adding such definition in our lockdep.h to cover older kernels. Signed-off-by: Arend van Spriel <arend.vanspriel@broadcom.com>
2019-06-27backport: check for failure when allocating ops in genetlinkLuca Coelho
We were not checking if the allocation failed in backport_genl_register_family(), which could lead to NULL pointer dereferences later. Fix that. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-06-27backport: rcupdate: add rcu_head_init and rcu_head_after_call_rcuArend van Spriel

2019-03-28backports: Build CONFIG_MT7603E only for kernel >= 4.2Hauke Mehrtens
The mt76 core driver makes use of struct page_frag_cache which was only added with kernel 4.2, deactivate all modules of the mt76 driver on older kernel versions. CONFIG_MT7603E was newly added in this kernel version. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2019-03-28backports: Add missing include for brcmfmacHauke Mehrtens
When building against kernel 4.8, 3.14 and older, brcmfmac failed because struct sk_buff was not declared in brcmfmac/bus.h. This is used in the brcmf_bus_ops.txdata() callback. I do not know why this was working before. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2019-03-28backports: Add smp_acquire__after_ctrl_dep()Hauke Mehrtens
smp_acquire__after_ctrl_dep() was introduced in kernel 4.8 in upstream Linux commit 33ac279677d ("locking/barriers: Introduce smp_acquire__after_ctrl_dep()") and is used by backports lib-refcount.c implementation now. This just adds the default implementation to backports. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2019-03-28backports: Add rhashtable_lookup_get_insert_fast()Hauke Mehrtens
rhashtable_lookup_get_insert_fast() was added in kernel 4.12 in Linux upstream commit f9fe1c12d12 ("rhashtable: Add rhashtable_lookup_get_insert_fast") It is now used by mac80211. For kernel < 4.9 we already backport the complete rhashtable implementation, so this is only needed for kernels more recent than 4.9. This is copied from upstreamn Linux kernel. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

2019-03-28backports: update iwlwifi pci device removal patch for v5.0Luca Coelho
The code surrounding the #ifdef we add has changed. Update the patch accordingly. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-03-28backports: genetlink: avoid NULL dereferenceJohannes Berg
If we fail to allocate extack, we fall back to the code path that tries to send an error *with* extack, but that will access our extack pointer. It also doesn't make sense, so just return an error back to netlink immediately and let it handle sending the error message to userspace.

2019-03-28backport: fix handling of nospec.h for 4.15.0 and 4.15.1Luca Coelho
The patch that introduces nospec.h was cherry-picked for 4.15 only in 4.15.2, so we need to adjust the ifdefs of our stub. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-03-28backport: add include ftrace_event.h back to backport-4.0.cLuca Coelho
At least one function, namely ftrace_print_array_seq(), still needs the ftrace_event.h header file, otherwise sparse may warning that it is declared as non-static without pre-declaration. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2019-03-20backport: add v5.* to the MakefileLuca Coelho
Now that 4.21 became 5.0, we need to update the Makefile accordingly. Stop looking at 4.19 for the 4.* series and add 5.*. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2019-01-26backports: Remove get_user_pages() functionsHauke Mehrtens
These functions are not used by any driver any more, remove them. They were introduced for the frame vector code which was used by the media subsystem. They also case some compile problems with kernel 4.4 which get fixed by just removing this code. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-06backports: build LIB80211 on kernel < 4.3 againv4.20-rc5-1Hauke Mehrtens
lib80211 does not use skcipher any more, build these modules again on older kernels without skcipher. ipw2x00 uses DRIVER_ATTR_RW which does not compile on kernel 3.10, require at least kernel 3.11. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

2018-12-06backports: Remove unused code from backport-public_key.hHauke Mehrtens
These functions declared in backport-public_key.h are not implemented in backports, and they were causing warnings because kernel_pkey_params was not declared before. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-06backports: Make TI WLCORE depend on kernel >= 4.2Hauke Mehrtens

2018-12-06backports: Add device_get_mac_address()Hauke Mehrtens
This was added in upstream commit 4c96b7dc0d39 ("Add a matching set of device_ functions for determining mac/phy") and is used by ath10k now. In the mainline kernel it uses device_property_read_u8_array(), but that was only introduced in kernel 3.18, use of_property_read_u8_array() only on all kernel versions where this backport is needed which was added much earlier. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-06backports: Add missing include for mt76Hauke Mehrtens
Without the inclusion of linux/module.h, MODULE_FIRMWARE was not declared when compiling against some kernel versions, add it. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-06backports: Add page_frag_alloc() and __page_frag_cache_drain()Hauke Mehrtens
This was introduced in kernel commit 8c2dd3e4a4b ("mm: rename __alloc_page_frag to page_frag_alloc and __free_page_frag to page_frag_free") and commit 44fdffd7050 ("mm: add support for releasing multiple instances of a page") and is used by the mt76 driver. Backporting it to kernel older than 4.2 is harder so just do it till that version. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-06backports: Add page_ref_count() and page_ref_sub_and_test()Hauke Mehrtens

2018-12-06backports: Remove BPAUTO_CRYPTO_SKCIPHERHauke Mehrtens
This was added in commit 32751c901728 ("backport: add crypto skcipher interface"), but all the drivers which need it were deactivated in commit cdcec8e6128 ("backports: disable things needing LIB80211 unless SKCIPHER can exist") because it does not compile any more. Remove this code now completely from the tree. lib80211 does not use skcipher any more, but directly uses the crpyto API. since kernel 4.20. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-03backports: Revert "dependencies: Make WIL6210 depend on kernel >= 4.8"Hauke Mehrtens
pci_alloc_irq_vectors() was added in commit 162a6b312f1 ("add support for pci_alloc_irq_vectors"), with this backport the WIL6210 driver works again. This reverts commit fbafdbe972402aad051d91d557f9cbb272844939. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
2018-12-03backports: Fix pci_alloc_irq_vectors() backportHauke Mehrtens
This copies the pci_alloc_irq_vectors() function from kernel 4.9 and replaces the __pci_enable_msi{x}_range() calls with calls to pci_enable_msi{x}_range(), these were backported to kernel versions < 3.14, so no need to handle the older kernels specially here. This also adds support for MSIx IRQs and adds the PCI_IRQ_* defines.

add support for function in kernels under 4.8 function is a wrapper around 'pci_enable_msi_block' or 'pci_enable_msi_range' depending on the kernel version the min\max number of interrupts was overridden to always use the max number of interrupts which seems correct since it was not supported in the old APIs Signed-off-by: Omer Dagan <omer.dagan@tandemg.com> [use GPL expert as everything in backports, remove unused ifdef] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2018-11-05backports: check if genl pre_doit and post_doit are setLuca Coelho
In the pre_doit and post_doit backports, we set the ops to our backported version, so genetlink itself will always call it. But then we don't check if the actual ops are set before calling them, which causes a call to a NULL pointer. Fix this by checking if the ops are actually set before calling them.

2018-10-02Revert "backports: crypto_memneq has been backported to 3.12 and 3.10"Johannes Berg
This reverts commit 1b481348b4564970e3cfa04023f1cc22ce2b6931. It actually broke the build to include this, as memneq.c is always built for kernels < 3.13, and thus we get a duplicate symbol export if we skip the backport definitions. Easier than making the build system depend on the strange versions is to just always use our backported version with symbol rename. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
