2020-07-20mISDN: 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. When memory is allocated in 'setup_hw()' (hfcpci.c) GFP_KERNEL can be used because it is called from the probe function and no lock is taken. The call chain is: hfc_probe() --> setup_card() --> setup_hw() When memory is allocated in 'inittiger()' (netjet.c) GFP_ATOMIC must be used because a spin_lock is taken by the caller (i.e. 'nj_init_card()') This is also consistent with the other allocations done in the function. @@ @@ - 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: David S.

2020-07-13isdn/capi: Replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2019-12-11isdn: capi: dead code removalArnd Bergmann
The staging isdn drivers are gone, and CONFIG_BT_CMTP is now the only user. This means a lot of the code in the subsystem has no remaining callers and can be removed. Change the capi user space front-end to be part of kernelcapi, and the combined module to only be compiled if BT_CMTP is also enabled, then remove the interfaces that have no remaining callers. As the notifier list and the capi_drivers list have no callers outside of kcapi.c, the implementation gets much simpler. Some definitions from the include/linux/*.h headers are only needed internally and are moved to kcapi.h.

2019-10-23compat_ioctl: move isdn/capi ioctl translation into driverArnd Bergmann
Neither the old isdn4linux interface nor the newer mISDN stack ever had working 32-bit compat mode as far as I can tell. However, the CAPI stack has some ioctl commands that are correctly listed in fs/compat_ioctl.c. We can trivially move all of those into the corresponding file that implement the native handlers by adding a compat_ioctl redirect to that. I did notice that treating CAPI_MANUFACTURER_CMD() as compatible is broken, so I'm also adding a handler for that, realizing that in all likelyhood, nobody is ever going to call it.

Then, fifo->iso[i].urb is used at some places, such as: LINE 1405: fill_isoc_urb(fifo->iso[i].urb, ...) urb->number_of_packets = num_packets; urb->transfer_flags = URB_ISO_ASAP; urb->actual_length = 0; urb->interval = interval; LINE 1416: fifo->iso[i].urb->... LINE 1419: fifo->iso[i].urb->... Thus, possible null-pointer dereferences may occur. To fix these bugs, "continue" is added to avoid using fifo->iso[i].urb when it is NULL.

The mISDN driver was added on those commits: 960366cf8dbb ("Add mISDN DSP") 1b2b03f8e514 ("Add mISDN core files") 04578dd330f1 ("Define AF_ISDN and PF_ISDN") e4ac9bc1f668 ("Add mISDN driver") None of them added a Documentation/isdn/mISDN.cert file. Also, whatever were supposed to be written there on that time, probably doesn't make any sense nowadays, as I doubt isdn would have any massive changes.

https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground Arnd Bergmann says: ==================== isdn: deprecate non-mISDN drivers When isdn4linux came up in the context of another patch series, I remembered that we had discussed removing it a while ago. It turns out that the suggestion from Karsten Keil wa to remove I4L in 2018 after the last public ISDN networks are shut down. This has happened now (with a very small number of exceptions), so I guess it's time to try again. We currently have three ISDN stacks in the kernel: the original isdn4linux (with the hisax driver), the newer CAPI (with four drivers), and finally the mISDN stack (supporting roughly the same hardware as hisax). As far as I can tell, anyone using ISDN with mainline kernel drivers in the past few years uses mISDN, and this is typically used for voice-only PBX installations that don't require a public network. The older stacks support additional features for data networks, but those typically make no sense any more if there is no network to connect to. My proposal for this time is to kill off isdn4linux entirely, as it seems to have been unusable for quite a while. This code has been abandoned for many years and it does cause problems for treewide maintenance as it tends to do everything that we try to stop doing. Birger Harzenetter mentioned that is is still using i4l in order to make use of the 'divert' feature that is not part of mISDN, but has otherwise moved on to mISDN for normal operation, like apparently everyone else. CAPI in turn is not quite as obsolete, but two of the drivers (avm and hysdn) don't seem to be used at all, while another one (gigaset) will stop being maintained as Paul Bolle is no longer able to test it after the network gets shut down in September. All three are now moved into drivers/staging to let others speak up in case there are remaining users. This leaves Bluetooth CMTP as the only remaining user of CAPI, but Marcel Holtmann wishes to keep maintaining it. For the discussion on version 1, see [2] Unfortunately, Karsten Keil as the maintainer has not participated in the discussion.

2019-05-31isdn: move capi drivers to stagingArnd Bergmann
I tried to find any indication of whether the capi drivers are still in use, and have not found anything from a long time ago. With public ISDN networks almost completely shut down over the past 12 months, there is very little you can actually do with this hardware. The main remaining use case would be to connect ISDN voice phones to an in-house installation with Asterisk or LCR, but anyone trying this in turn seems to be using either the mISDN driver stack, or out-of-tree drivers from the hardware vendors. I may of course have missed something, so I would suggest moving these three drivers (avm, hysdn, gigaset) into drivers/staging/ just in case someone still uses them. If nobody complains, we can remove them entirely in six months, or otherwise move the core code and any drivers that are still needed back into drivers/isdn. As Paul Bolle notes, he is still testing the gigaset driver as long as he can, but the Dutch ISDN network will be shut down in September 2019, which puts an end to that. Marcel Holtmann still maintains the Bluetooth CMTP profile and wants to keep that alive, so the actual CAPI subsystem code remains in place for now, after all other drivers are gone, CMTP and CAPI can be merged into a single driver directory.

2019-05-31isdn: remove isdn4linuxArnd Bergmann
With all isdn4linux hardware drivers gone, this is only a wrapper around CAPI to support old user space. However, from looking at the mailing list, it seems that the last time anyone asked about it was in 2014, when the upgrade from a linux-2.4 installation failed, and mISDN was suggested as a replacement. The largest public ISDN network (Deutsche Telekom) was supposed to be shut down 2018, which must have drastically reduced the number of legacy installations. When we last discussed removing i4l in 2016, Karsten Keil suggested revisiting this in 2018. I guess this is overdue.

2019-05-31isdn: remove hisax driverArnd Bergmann
With the decline of ISDN, this seems to have become almost completely obsolete, and even in the past years before that, almost all remaining users appear to have used mISDN instead. Birger Harzenetter noted that he is still using i4l/hisax to take advantage of the 'divert' driver for call diversion, but otherwise uses mISDN on the same hardware. This is a rare edge case as far as I can tell, but we are still breaking an actively used work flow (see https://xkcd.com/1172/). We debated moving i4l/hisax to staging as an intermediate step, but as he is not likely to change the setup, and that would just delay breaking this use case. The alternatives here are to stay on stable kernels < 5.2, to create an external driver repository for isdn4linux, or to add divert functionality to mISDN.

The user can change the device_name with the IMSETDEVNAME ioctl, but we need to ensure that the user's name is NUL terminated. Otherwise it could result in a buffer overflow when we copy the name back to the user with IMGETDEVINFO ioctl. I also changed two strcpy() calls which handle the name to strscpy(). Hopefully, there aren't any other ways to create a too long name, but it's nice to do this as a kernel hardening measure.
