2020-11-07rtlwifi: Remove in_interrupt() usage in halbtc_send_bt_mp_operation()Sebastian Andrzej Siewior
halbtc_send_bt_mp_operation() uses in_interrupt() to determine if it is safe to invoke wait_for_completion(). The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. Aside of that in_interrupt() is not correct as it does not catch preempt disabled regions which neither can sleep. halbtc_send_bt_mp_operation() is called from: rtl_watchdog_wq_callback() rtl_btc_periodical() halbtc_get() case BTC_GET_U4_BT_PATCH_VER: halbtc_get_bt_patch_version() which is preemtible context. rtl_c2h_content_parsing() btc_ops->btc_btinfo_notify() rtl_btc_btinfo_notify() exhalbtc_bt_info_notify() ex_btc8723b1ant_bt_info_notify() ex_btc8821a1ant_bt_info_notify() ex_btc8821a2ant_bt_info_notify() btcoexist->btc_set_bt_reg() halbtc_set_bt_reg() rtl_c2h_content_parsing() is in turn called from: rtl_c2hcmd_wq_callback() rtl_c2hcmd_launcher() which is preemptible context and from: _rtl_pci_rx_interrupt rtl_c2hcmd_enqueue() which is obviously not preemptible but limited to C2H_BT_MP commands which does invoke rtl_c2h_content_parsing().

2020-11-07rtlwifi: Remove in_interrupt() usage in is_any_client_connect_to_ap().Sebastian Andrzej Siewior
is_any_client_connect_to_ap() is using in_interrupt() to determine whether it should acquire the lock prior accessing the list. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The function is called from: - halbtc_get() - halbtc_get() halbtc_get_wifi_link_status() - halbtc_display_dbg_msg() halbtc_display_wifi_status() halbtc_get_wifi_link_status() All top level callers are part of the btc_coexist callback inferface and are never invoked from a context which can hold the lock already. The contexts which hold the lock are either protecting list add/del operations or list walks which never call into any of the btc_coexist interfaces. In fact the conditional is outright dangerous because if this function would be invoked from a BH disabled context the check would avoid taking the lock while on another CPU the list could be manipulated under the lock. Remove the in_interrupt() check and always acquire the lock. To simplify the code further use list_empty() instead of walking the list and counting the entries just to check the count for > 0 at the end.

2020-11-07rtlwifi: Fix non-canonical address access issuesWeitaoWangoc
During realtek USB wireless NIC initialization, it's unexpected disconnection will cause urb sumbmit fail. On the one hand, _rtl_usb_cleanup_rx will be called to clean up rx stuff, especially for rtl_wq. On the other hand, disconnection will cause rtl_usb_disconnect and _rtl_usb_cleanup_rx to be called. So, rtl_wq will be flush/destroy twice, which will cause non-canonical address 0xdead000000000122 access and general protection fault. Fixed this issue by remove _rtl_usb_cleanup_rx when urb sumbmit fail.

2020-09-29net: rtlwifi: Replace in_interrupt() for context detectionSebastian Andrzej Siewior
rtl_lps_enter() and rtl_lps_leave() are using in_interrupt() to detect whether it is safe to acquire a mutex or if it is required to defer to a workqueue. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be seperated or the context be conveyed in an argument passed by the caller, which usually knows the context. in_interrupt() also is only partially correct because it fails to chose the correct code path when just preemption or interrupts are disabled. Add an argument 'may_block' to both functions and adjust the callers to pass the context information. The following call chains were analyzed to be safe to block: rtl_watchdog_wq_callback() rlf_lps_leave/enter() rtl_op_suspend() rtl_lps_leave() rtl_op_bss_info_changed() rtl_lps_leave() rtl_op_sw_scan_start() rtl_lps_leave() The following call chains were analyzed to be unsafe to block: _rtl_pci_interrupt() _rtl_pci_rx_interrupt() rtl_lps_leave() _rtl_pci_interrupt() _rtl_pci_rx_interrupt() rtl_is_special_data() rtl_lps_leave() _rtl_pci_interrupt() _rtl_pci_rx_interrupt() rtl_is_special_data() setup_special_tx() rtl_lps_leave() _rtl_pci_interrupt() _rtl_pci_tx_isr rtl_lps_leave() halbtc_leave_lps() rtl_lps_leave() This leaves four callers of rtl_lps_enter/leave() where the analyzis stopped dead in the maze of several nested pointer based callchains and lack of rtlwifi hardware to debug this via tracing: halbtc_leave_lps(), halbtc_enter_lps(), halbtc_normal_lps(), halbtc_pre_normal_lps() These four have been cautionally marked to be unable to block which is the safe option, but the rtwifi wizards should be able to clarify that.

2020-09-29net: rtlwifi: Remove in_interrupt() from debug macroSebastian Andrzej Siewior
The usage of in_interrupt() in drivers in is phased out. rtl_dbg() a printk based debug aid is using in_interrupt() in the underlying C function _rtl_dbg_out() which is almost identical to _rtl_dbg_print(). The only difference is the printout of in_interrupt(). The decoding of in_interrupt() as hexvalue is non-trivial and aside of being phased out for driver usage the return value is just by chance the masked preempt count value and not a boolean. These home brewn printk debug aids are tedious to work with and provide only minimal context. They should be replaced by trace_printk() or a debug tracepoint which automatically records all context information. To make progress on the in_interrupt() cleanup, make rtl_dbg() use _rtl_dbg_print() and remove _rtl_dbg_out().

2020-09-29net: rtlwifi: Remove void* casts related to delayed workSebastian Andrzej Siewior
INIT_DELAYED_WORK() takes two arguments: A pointer to the delayed work and a function reference for the callback. The rtl code casts all function references to (void *) because the callbacks in use are not matching the required function signature. That's error prone and bad pratice. Some of the callback functions are also global, but only used in a single file. Clean the mess up by: - Adding the proper arguments to the callback functions and using them in the container_of() constructs correctly which removes the hideous container_of_dwork_rtl() macro as well. - Removing the type cast at the initializers - Making the unnecessary global functions static Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Kalle Valo <kvalo@codeaurora.org> Signed-off-by: David S.

2020-09-09rtlwifi: switch from 'pci_' to 'dma_' APIChristophe JAILLET
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. The only file where some GFP_ flags are updated is 'pci.c'. When memory is allocated in '_rtl_pci_init_tx_ring()' and '_rtl_pci_init_rx_ring()' GFP_KERNEL can be used because both functions are called from a probe function and no spinlock is taken. The call chain is: rtl_pci_probe --> rtl_pci_init --> _rtl_pci_init_trx_ring --> _rtl_pci_init_rx_ring --> _rtl_pci_init_tx_ring @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200907193828.318233-1-christophe.jaillet@wanadoo.fr
