[PATCH] net: don't unconditionally copy_from_user a struct ifreq for socket ioctls

by Peter Collingbourne

A common implementation of isatty(3) involves calling a ioctl passing a dummy struct argument and checking whether the syscall failed -- bionic and glibc use TCGETS (passing a struct termios), and musl uses TIOCGWINSZ (passing a struct winsize). If the FD is a socket, we will copy sizeof(struct ifreq) bytes of data from the argument and return -EFAULT if that fails. The result is that the isatty implementations may return a non-POSIX-compliant value in errno in the case where part of the dummy struct argument is inaccessible, as both struct termios and struct winsize are smaller than struct ifreq (at least on arm64). Although there is usually enough stack space following the argument on the stack that this did not present a practical problem up to now, with MTE stack instrumentation it's more likely for the copy to fail, as the memory following the struct may have a different tag. Fix the problem by adding an early check for whether the ioctl is a valid socket ioctl, and return -ENOTTY if it isn't.

If the driver flushes data to the line discipline receive_buf() method while tiocsti() is waiting for the ops->receive_buf() to finish its work, the data race will happen. For example: tty_ioctl |tty_ldisc_receive_buf ->tioctsi | ->tty_port_default_receive_buf | ->tty_ldisc_receive_buf ->hci_uart_tty_receive | ->hci_uart_tty_receive ->h4_recv | ->h4_recv In this case, the h4 receive buffer will be overwritten by the latecomer, and we will lost the data. Hence, change tioctsi() function to use the exclusive lock interface from tty_buffer to avoid the data race.

Only TDs with status TD_CLEARING_CACHE will be given back after cache is cleared with a set TR deq command. xhci_invalidate_cached_td() failed to set the TD_CLEARING_CACHE status for some cancelled TDs as it assumed an endpoint only needs to clear the TD it stopped on. This isn't always true. For example with streams enabled an endpoint may have several stream rings, each stopping on a different TDs. Note that if an endpoint has several stream rings, the current code will still only clear the cache of the stream pointed to by the last cancelled TD in the cancel list. This patch only focus on making sure all canceled TDs are given back, avoiding hung task after device removal. Another fix to solve clearing the caches of all stream rings with cancelled TDs is needed, but not as urgent.

patch "xhci: fix unsafe memory usage in xhci tracing" added to usb-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled xhci: fix unsafe memory usage in xhci tracing to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From cbf286e8ef8337308c259ff5b9ce2e74d403be5a Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Fri, 20 Aug 2021 15:34:58 +0300 Subject: xhci: fix unsafe memory usage in xhci tracing Removes static char buffer usage in the following decode functions: xhci_decode_trb() xhci_decode_ptortsc() Caller must provide a buffer to use. In tracing use __get_str() as recommended to pass buffer. Minor chanes are needed in xhci debugfs code as these functions are also used there. Changes include moving XHCI_MSG_MAX definititon from xhci-trace.h to xhci.h Cc: <stable(a)vger.kernel.org> Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> Link: https://lore.kernel.org/r/20210820123503.2605901-2-mathias.nyman@linux.inte… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/usb/host/xhci-debugfs.c | 6 ++-- drivers/usb/host/xhci-trace.h | 8 ++--- drivers/usb/host/xhci.h | 52 ++++++++++++++++++--------------- 3 files changed, 36 insertions(+), 30 deletions(-) diff --git a/drivers/usb/host/xhci-debugfs.c b/drivers/usb/host/xhci-debugfs.c index 2c0fda57869e..85c12f56b17c 100644 --- a/drivers/usb/host/xhci-debugfs.c +++ b/drivers/usb/host/xhci-debugfs.c @@ -198,12 +198,13 @@ static void xhci_ring_dump_segment(struct seq_file *s, int i; dma_addr_t dma; union xhci_trb *trb; + char str[XHCI_MSG_MAX]; for (i = 0; i < TRBS_PER_SEGMENT; i++) { trb = &seg->trbs[i]; dma = seg->dma + i * sizeof(*trb); seq_printf(s, "%pad: %s\n", &dma, - xhci_decode_trb(le32_to_cpu(trb->generic.field[0]), + xhci_decode_trb(str, XHCI_MSG_MAX, le32_to_cpu(trb->generic.field[0]), le32_to_cpu(trb->generic.field[1]), le32_to_cpu(trb->generic.field[2]), le32_to_cpu(trb->generic.field[3]))); @@ -341,9 +342,10 @@ static int xhci_portsc_show(struct seq_file *s, void *unused) { struct xhci_port *port = s->private; u32 portsc; + char str[XHCI_MSG_MAX]; portsc = readl(port->addr); - seq_printf(s, "%s\n", xhci_decode_portsc(portsc)); + seq_printf(s, "%s\n", xhci_decode_portsc(str, portsc)); return 0; } diff --git a/drivers/usb/host/xhci-trace.h b/drivers/usb/host/xhci-trace.h index 627abd236dbe..5e1c50cb7016 100644 --- a/drivers/usb/host/xhci-trace.h +++ b/drivers/usb/host/xhci-trace.h @@ -25,8 +25,6 @@ #include "xhci.h" #include "xhci-dbgcap.h" -#define XHCI_MSG_MAX 500 - DECLARE_EVENT_CLASS(xhci_log_msg, TP_PROTO(struct va_format *vaf), TP_ARGS(vaf), @@ -122,6 +120,7 @@ DECLARE_EVENT_CLASS(xhci_log_trb, __field(u32, field1) __field(u32, field2) __field(u32, field3) + __dynamic_array(char, str, XHCI_MSG_MAX) ), TP_fast_assign( __entry->type = ring->type; @@ -131,7 +130,7 @@ DECLARE_EVENT_CLASS(xhci_log_trb, __entry->field3 = le32_to_cpu(trb->field[3]); ), TP_printk("%s: %s", xhci_ring_type_string(__entry->type), - xhci_decode_trb(__entry->field0, __entry->field1, + xhci_decode_trb(__get_str(str), XHCI_MSG_MAX, __entry->field0, __entry->field1, __entry->field2, __entry->field3) ) ); @@ -523,6 +522,7 @@ DECLARE_EVENT_CLASS(xhci_log_portsc, TP_STRUCT__entry( __field(u32, portnum) __field(u32, portsc) + __dynamic_array(char, str, XHCI_MSG_MAX) ), TP_fast_assign( __entry->portnum = portnum; @@ -530,7 +530,7 @@ DECLARE_EVENT_CLASS(xhci_log_portsc, ), TP_printk("port-%d: %s", __entry->portnum, - xhci_decode_portsc(__entry->portsc) + xhci_decode_portsc(__get_str(str), __entry->portsc) ) ); diff --git a/drivers/usb/host/xhci.h b/drivers/usb/host/xhci.h index 3c7d281672ae..99ae9994f5eb 100644 --- a/drivers/usb/host/xhci.h +++ b/drivers/usb/host/xhci.h @@ -22,6 +22,9 @@ #include "xhci-ext-caps.h" #include "pci-quirks.h" +/* max buffer size for trace and debug messages */ +#define XHCI_MSG_MAX 500 + /* xHCI PCI Configuration Registers */ #define XHCI_SBRN_OFFSET (0x60) @@ -2235,15 +2238,14 @@ static inline char *xhci_slot_state_string(u32 state) } } -static inline const char *xhci_decode_trb(u32 field0, u32 field1, u32 field2, - u32 field3) +static inline const char *xhci_decode_trb(char *str, size_t size, + u32 field0, u32 field1, u32 field2, u32 field3) { - static char str[256]; int type = TRB_FIELD_TO_TYPE(field3); switch (type) { case TRB_LINK: - sprintf(str, + snprintf(str, size, "LINK %08x%08x intr %d type '%s' flags %c:%c:%c:%c", field1, field0, GET_INTR_TARGET(field2), xhci_trb_type_string(type), @@ -2260,7 +2262,7 @@ static inline const char *xhci_decode_trb(u32 field0, u32 field1, u32 field2, case TRB_HC_EVENT: case TRB_DEV_NOTE: case TRB_MFINDEX_WRAP: - sprintf(str, + snprintf(str, size, "TRB %08x%08x status '%s' len %d slot %d ep %d type '%s' flags %c:%c", field1, field0, xhci_trb_comp_code_string(GET_COMP_CODE(field2)), @@ -2273,7 +2275,8 @@ static inline const char *xhci_decode_trb(u32 field0, u32 field1, u32 field2, break; case TRB_SETUP: - sprintf(str, "bRequestType %02x bRequest %02x wValue %02x%02x wIndex %02x%02x wLength %d length %d TD size %d intr %d type '%s' flags %c:%c:%c", + snprintf(str, size, + "bRequestType %02x bRequest %02x wValue %02x%02x wIndex %02x%02x wLength %d length %d TD size %d intr %d type '%s' flags %c:%c:%c", field0 & 0xff, (field0 & 0xff00) >> 8, (field0 & 0xff000000) >> 24, @@ -2290,7 +2293,8 @@ static inline const char *xhci_decode_trb(u32 field0, u32 field1, u32 field2, field3 & TRB_CYCLE ?
