Public bug reported:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows
*** Error in `./x86_64-softmmu/qemu-system-x86_64': free(): invalid next size (normal): 0x00007f66d80b7300 ***

Title:
Guest(ubuntu 18.04) crashes when trying uploading file
Status in QEMU:
Confirmed
Bug description:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows
*** Error in `./x86_64-softmmu/qemu-system-x86_64': free(): invalid next size (normal): 0x00007f66d80b7300 ***

Looks like it might be e1000e specific?
I can recreate it with either q35 with no extra options (it has e1000e by default), pc or q35 specifying e1000e, but plain pc works fine.
Simple test; scp bigfile from guest to user@10.0.2.2: (i.e. host)

-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows

It's indeed e1000e specific, when I change e1000e to e1000, I can upload

e1000e,netdev=realnet0
The trace is as follows

Hi,
I have find the overflow point using ASAN.
void
m_cat(struct mbuf *m, struct mbuf *n)
{
/*
* If there's no room, realloc
*/
if (M_FREEROOM(m) < n->m_len)
m_inc(m, m->m_len + n->m_len);
memcpy(m->m_data+m->m_len, n->m_data, n->m_len);
m->m_len += n->m_len;
m_free(n);
}
/* make m 'size' bytes large from m_data */
void
m_inc(struct mbuf *m, int size)
{
int datasize;
/* some compilers throw up on gotos. This one we can fake. */
if (m->m_size > size) {
return;
}
if (m->m_flags & M_EXT) {
datasize = m->m_data - m->m_ext;
m->m_ext = g_realloc(m->m_ext, size + datasize);
} else {
datasize = m->m_data - m->m_dat;
m->m_ext = g_malloc(size + datasize);
memcpy(m->m_ext, m->m_dat, m->m_size);
m->m_flags |= M_EXT;
}
m->m_data = m->m_ext + datasize;
m->m_size = size + datasize;
}
Here m_cat catenates two mbuf, when the first has no buffer, it allocates an M_EXT.
In m_inc, g_malloc called, then return m_cat, the next call to m_cat will trigger oob write.
Seems the m_len is too big.
In my debug, I see the m->m_len is 0x5b0, but datasize in m_inc is 0x40. Is this right?
Thanks,
Li Qiang

It's indeed e1000e specific, when I change e1000e to e1000, I can upload
file freely. Looks like there is an overflow somewhere in e1000e that
corrupted the heap chunk header.

Title:
Guest(ubuntu 18.04) crashes when trying uploading file
Status in QEMU:
Confirmed
Bug description:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows

Hi,
I have find the overflow point using ASAN.
void
m_cat(struct mbuf *m, struct mbuf *n)
{
/*
* If there's no room, realloc
*/
if (M_FREEROOM(m) < n->m_len)
m_inc(m, m->m_len + n->m_len);
memcpy(m->m_data+m->m_len, n->m_data, n->m_len);
m->m_len += n->m_len;
m_free(n);
}
/* make m 'size' bytes large from m_data */
void
m_inc(struct mbuf *m, int size)
{
int datasize;
/* some compilers throw up on gotos. This one we can fake. */
if (m->m_size > size) {
return;
}
if (m->m_flags & M_EXT) {
datasize = m->m_data - m->m_ext;
m->m_ext = g_realloc(m->m_ext, size + datasize);
} else {
datasize = m->m_data - m->m_dat;
m->m_ext = g_malloc(size + datasize);
memcpy(m->m_ext, m->m_dat, m->m_size);
m->m_flags |= M_EXT;
}
m->m_data = m->m_ext + datasize;
m->m_size = size + datasize;
}
Here m_cat catenates two mbuf, when the first has no buffer, it allocates an M_EXT.
In m_inc, g_malloc called, then return m_cat, the next call to m_cat will trigger oob write.
Seems the m_len is too big.
In my debug, I see the m->m_len is 0x5b0, but datasize in m_inc is 0x40. Is this right?
Thanks,
Li Qiang

Title:
Guest(ubuntu 18.04) crashes when trying uploading file
Status in QEMU:
Confirmed
Bug description:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows
*** Error in `./x86_64-softmmu/qemu-system-x86_64': free(): invalid next size (normal): 0x00007f66d80b7300 ***

For me:
c22098c74a fails
864036e251 fails
3835c310bd doesn't crash, but sometimes the outbound connection hangs.
So perhaps the crash is 864036e251f54c99d31df124aad7f34f01f5344c

Bug description:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows
*** Error in `./x86_64-softmmu/qemu-system-x86_64': free(): invalid next size (normal): 0x00007f66d80b7300 ***

Status in QEMU:
Confirmed
Bug description:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows

-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows

Status in QEMU:
Fix Released
Bug description:
I speficy slirp network, and I can open websites, git clone repos. But
when I try to upload a file to slack, or try to do a git push, it
crashes.
My host is ubuntu 16.04 with kernel 4.15.0-29-generic, and qemu is
latest source in git(commit 1fb57da72ae0886e). The command I use is
./x86_64-softmmu/qemu-system-x86_64 -machine q35,accel=kvm -m 2048
-drive file=../qcow2/guest.qcow2 -netdev user,id=realnet0 -device
e1000e,netdev=realnet0
The trace is as follows
*** Error in `./x86_64-softmmu/qemu-system-x86_64': free(): invalid next size (normal): 0x00007f66d80b7300 ***
