2020-04-14lp/drivers/usb: Work around QEMU XHCI register issueDuncan Laurie
The QEMU XHCI controller does not support byte/word reads from the capability register and it expects dword reads only. In order to make this work move the access of the capability register fields to use macros instead of a packed struct bitfield. This issue was filed upstream: https://bugs.launchpad.net/qemu/+bug/1693050 The original fix attempt in 2012 was not effective: https://github.com/qemu/qemu/commit/6ee021d41078844df60a3a466e3829a3e82776f3 With this change the controller is detected properly by the libpayload USB drivers.

2020-04-03libpayload: malloc: Change memcpy() to memmove() in reallocJulius Werner
Our realloc() works (somewhat suboptimally) by free()ing the existing allocation and then reallocating it wherever it fits. If there was free space before the old location, this means the new allocation may be before the old one, and if the free space block is smaller than the old allocation it may overlap. Thus, we should be moving memmove() instead of memcpy() to move the block over. This is not a problem in practice since all our existing memcpy()s are simple iterate and copy front to back implementations which are safe for overlaps when the destination is in front of the source. but it's still the more correct thing to do (in case we ever change our memcpy()s to do something more advanced or whatever).

2020-03-02libpayload: cbfs: fix infinite loop in cbfs_get_{handle,attr}Alex Rebert
cbfs_get_handle() and cbfs_get_attr() are both looping over elements to find a particular one. Each element header contains the element's length, which is used to compute the next element's offset. Invalid or corrupted CBFS files could lead to infinite loops where the offset would remain constant across iterations, due to 0-length elements or integer overflows in the computation of the next offset. This patch makes both functions more robust by adding a check that ensure offsets are strictly monotonic. Instead of infinite looping, the functions are now printing an ERROR and returning a NULL value.

This patch makes libpayload enable the instruction cache as the very first thing, which is similar to how we treat it in coreboot. It also prevents the icache from being disabled again during mmu_disable() as part of the two-stage page table setup in post_sysinfo_scan_mmu_setup(). It replaces the existing mmu_disable() implementation with the assembly version from coreboot which handles certain edge cases better (see CB:27238 for details). The SCTLR flag definitions in libpayload seem to have still been copy&pasted from arm32, so replace with the actual arm64 defintions from coreboot.

2019-12-11printf: Automatically prefix %p with 0xJulius Werner
According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

2019-12-05arm64: Bump exception stack size to 2KBJulius Werner
To avoid trampling over interesting exception artifacts on the real stack, our arm64 systems switch to a separate exception stack when entering an exception handler. We don't want that to use up too much SRAM so we just set it to 512 bytes. I mean it just prints a bunch of registers, how much stack could it need, right? Quite a bit it turns out. The whole vtxprintf() call stack goes pretty deep, and aarch64 generally seems to be very generous with stack space. Just the varargs handling seems to require 128 bytes for some reason, and the other stuff adds up too. In the end the current implementation takes 1008 bytes, so bump the exception stack size to 2K to make sure it fits.

2019-09-18libpayload: Use interrupt transfers for USB hubsNico Huber
In interactive payloads, the USB stack's poll procedure is implicitly called from the UI loop. Since all USB control transfers are handled synchronously, polling hubs with these slows the UI significantly down. So switch to interrupt transfers that are done asynchronously and only perform control transfers when the hub reported a status change. We use the interrupt endpoint's max packet size instead of the theo- retical transfer length of `(bNrPorts + 1) / 8` as Linux' code mentions hubs that return too much data.

2019-08-22libpayload: usbmsc: Factor out usb_msc_force_init() functionJulius Werner
We're planning to have a use case with a custom USB device that implements the USB mass storage protocol on its bulk endpoints, but does not have the normal MSC class/protocol interface descriptors and does not support class-specific control requests (Get Max LUN and Bulk-Only Reset). We'd like to identify/enumerate the device via usb_generic_create() in our payload but then reuse all the normal MSC driver code. In order to make that possible, this patch factors a new usb_msc_force_init() function out of usb_msc_init() which will initialize an MSC device without checking its descriptors. It also adds some "quirks" flags that allow devices registered this way to customize behavior of the MSC stack.

2019-08-22libpayload: usbmsc: Skip zero-length packets at end of dataJulius Werner
Some broken USB mass storage devices send another zero-length packet at the end of the data part of a transfer if the amount of data was evenly divisible by the packet size (which is pretty much always the case for block reads). This packet will get interpreted as the CSW and screw up the MSC state machine. This patch works around this issue by retrying the CSW transfer when it was received as exactly 0 bytes. This is the same mitigation the Linux kernel uses and harmless for correctly behaving devices. Also tighten validation of the CSW a little, making sure we verify the length before we read any fields and checking the signature in addition to the tag.

2019-08-22Add buffer_to/from_fifo32(_prefix) helpersJulius Werner
Many peripheral drivers across different SoCs regularly face the same task of piping a transfer buffer into (or reading it out of) a 32-bit FIFO register. Sometimes it's just one register, sometimes a whole array of registers. Sometimes you actually transfer 4 bytes per register read/write, sometimes only 2 (or even 1). Sometimes writes need to be prefixed with one or two command bytes which makes the actual payload buffer "misaligned" in relation to the FIFO and requires a bunch of tricky bit packing logic to get right. Most of the times transfer lengths are not guaranteed to be divisible by 4, which also requires a bunch of logic to treat the potential unaligned end of the transfer correctly. We have a dozen different implementations of this same pattern across coreboot. This patch introduces a new family of helper functions that aims to solve all these use cases once and for all (*fingers crossed*).

2019-07-23libpayload/libc: Correct strlcat return valueJacob Garber
The documented return value for strlcat is horribly wrong, as is the return value itself. It should not return the number of appended bytes, but rather the length of the concatenated string. From the man page: The strlcpy() and strlcat() functions return the total length of the string they tried to create. For strlcpy() that means the length of src. For strlcat() that means the initial length of dst plus the length of src. While this may seem somewhat confusing, it was done to make truncation detection simple. This change is more likely to fix existing code than break it, since anyone who uses the return value of strlcat will almost certainly rely on the standard behaviour rather than investigate coreboot's source code to see that we have a quirky version.

2019-06-04libpayload/i8042/keyboard: Fix return value check for keyboard_cmdFurquan Shaikh
CB:32951 ("libpayload: Reset PS/2 keyboard") added a call to reset keyboard and check the return value of keyboard_cmd() to compare against I8042_KBCMD_ACK. However, keyboard_cmd() already checks for ACK and returns 1 or 0 based on whether ACK is received. This change fixes the check introduced by CB:32951 to compare against 0 just like the other checks for keyboard_cmd(). Additionally, it adds error messages for all failed commands in keyboard_init() to make the prints consistent in case of failure.

2019-05-27libpayload: Reset PS/2 keyboardPaul Menzel
Loading a libpayload based payload like coreinfo or FILO from SeaBIOS or GRUB pressing keys does not give the expected results. For example, pressing F1 gives the character 24 translated to scan code 6a. ESC for example 43 (111) in coreinfo loaded from SeaBIOS on QEMU Q35. The problem is not reproducible using the payload directly, that means without SeaBIOS or GRUB. The problem seems to be, that those have already initialized the PS/2 controller and AT keyboard. Comparing it with coreboot’s PS/2 keyboard code, the keyboard needs to be reset. That seems to fix the issue, when the keyboard was initialized before. TEST=Build coreboot for QEMU Q35 with SeaBIOS, and coreinfo as secondary payload.

2019-04-04Make common macros double-evaluation safeJulius Werner
I just got hit by a double-evaluation bug again, it's time to attempt to fix this once more. Unfortunately there are several issues that don't make this easy: - bitfield variables don't support typeof() - local macro variables that shadow others trigger -Werror=shadow - sign warnings with integer literal and unsigned var in typeof-MIN() - ({ statement expressions }) can not be used outside functions - romcc doesn't support any of the fancy GCC/clang extensions This patch tries to address all of them as far as possible with macro magic. We don't have the technology to solve the bitfield and non-function context issues yet (__builtin_choose_expr() still throws a "no statement expression outside a function" error if it's only in the branch that's not chosen, unfortunately), so we'll have to provide alternative macros for use in those cases (and we'll avoid making __ALIGN_MASK() double-evaluation safe for now, since it would be annoying to do that there and having an alignment mask with side effects seems very unlikely). romcc can continue using unsafe versions since we're hopefully not writing a lot of new code for it. Sign warnings can be avoided in literal/variable comparisons by always using the type of the variable there. Shadowing is avoided by picking very explicit local variable names and using a special __COUNTER__ solution for MIN() and MAX() (the only ones of these you're likely to nest). Also add DIV_ROUND_UP() to libpayload since it's a generally quite useful thing to have.

2019-03-26libpayload: strtoull: Fix edge case bug with *endptrJulius Werner
strtoull() can optionally take a second pointer as an out-parameter that will be adjusted to point to the end of the parsed string. This works almost right, but misses two important edge cases: firstly,when the parsed string is "0", the function will interpret the leading '0' as an octal prefix, so that the first actually parsed digit is already the terminating '\0' byte. This will cause the function to early abort, which still (correctly) returns 0 but doesn't adjust *endptr. The early abort is pointless anyway -- the only other thing the function does is run a for-loop whose condition is the exact inverse (so it's guaranteed to run zero iterations in this case) and then adjust *endptr (which we want). So just take it out. This also technically corrects the behavior of *endptr for a completely invalid string, since the strtoull man page says > If there were no digits at all, strtoul() stores the original value of > nptr in *endptr (and returns 0). The second issue occurs when the parsed string is "0x" without another valid digit behind it. In this case, we will still jump over the 0x prefix so that *endptr is set to the first byte after that. The correct interpretation in this case is that there is no 0x prefix, and instead a valid 0 digit with the 'x' being invalid garbage at the end. By not skipping the prefix unless there's at least one valid digit after it, we get the correct behavior of *endptr pointing to the 'x'.
